Is your E-mail being delivered to your intended recipient(s)?
The simple answer is “not always.” Not only that, you will not always know whether or not that important piece of communication was delivered. Associations, their members, and their member’s clients all experience bounced, blocked, and undelivered e-mail issues.
For associations, this means you cannot always count on e-mail to reach your members even if you DO have their correct e-mail address. Whether you are working to move your association to online voting where e-mail notification is often important, or using e-mail for meeting notices and alerts, you cannot be certain the e-mail you send is being delivered to the intended parties. This is serious.
For your members, this means their clients may not receive e-mail promised by the member), resulting in a small but significant breach of trust as a promise made but not kept.
For your member’s clients who may have been promised listing information being sent directly from the MLS, the information flow is breached, and a sale possibly delayed.
How can we possibly expect REALTOR(S) and consumers to move towards online transactions when we cannot even insure that e-mail is being delivered...or can we?
The degree of damage undelivered e-mail causes is unmeasured, but one thing is certain, communication and information flow via e-mail has been impaired over the last 18 months.
Why is e-mail being blocked, resulting in undelivered communication?
In two words, SPAM and Viruses.
Too much e-mail is unsolicited, junk e-mail that chews up bandwidth, steals the time of those who must sort through it all, and creates storage problems.
Spam (unsolicited commercial e-mail) and e-mail borne viruses are threatening the usefulness of e-mail as a business communication tool. It has been reported by reputable sources based on numerous studies that close to 80% of all e-mail today is Spam, and it is affecting everyone's productivity and the quality of communication world wide. As horrendous as the spam problem has been for the last couple of years, it is getting noticeably worse by the day.
E-mail borne viruses are another problem. Today's viruses have the ability to "spoof" the "From" and "Subject" fields of an e-mail message which prevents you from knowing who really sent you the virus or the content of the e-mail. A virus goes into the address book of the newly infected computer, grabs an e-mail address at random and puts it in the "from field" of a new message. It then attaches a virus to the message, and sends the message to everyone in the e-mail address book of the newly infected computer.
There is no telling who sent you the virus. Familiar names are now a dangerous decoy, luring you into a false sense of security and tempting you to open infected e-mail.
If you are receiving e-mail from people, servers, or auto responders and you did not send an e-mail to generate a response, someone who has your e-mail address in their e-mail address book has been infected by a virus and your name was selected at random and placed in the “From” field of the e-mail launched from their infected computer. The e-mail sent from their computer triggered the response which is being sent not to the person who sent the e-mail, but to the person in the “From” field.
There is nothing you can do to prevent this, but you can protect yourself. Keep your virus protection software updated with the latest virus definitions. I have my computer set to scan on a regular basis and use the "Live Update" feature of my Norton Anti virus software. Run a complete virus scan if you ever suspect that you have a virus.
If your e-mail address is in the e-mail address books of others, there is a good chance that someday your e-mail address will appear in the "From" field of an infected e-mail and some of the recipients who do not understand the nature of today's e-mail viruses will think you sent them a virus. You can also count on receiving lots of e-mail you didn’t ask for.
Some Viruses (worms) turn your computer into an e-mail generator, sending itself to everyone in your address book. More “junk” e-mail even if it is detected by your antivirus software.
Can anything be done about the current e-mail problem?
E-mail users complain constantly about the state of affairs with e-mail and Spam and are ready to try anything, often without understanding that solutions to problems often create problems themselves. Many companies claim to have the prescription that will end the plague of Spam and many consumers are trying different solutions, both client side (on their computer) and server side (on their e-mail host's servers). It is important to keep in mind that different "prescriptions" (and combinations of prescriptions) carry different "side effects." Prescriptions and treatments always have side effects and you must weigh the benefits against the side effects and make your decision as to which solutions make the most sense.
The first and easiest solution is to get familiar with the delete key and simply delete the Spam you do not want. Do nothing to encourage Spammers. Do not respond to their solicitations or purchase their products.
If the "Delete Key" solution becomes too time consuming and burdensome, then consider both client side and server side solutions.
As previously mentioned, when looking for the right solution for your association or your member’s businesses, it is important to know about the side effects created by these solutions.
Both the e-mail sent to you by your clients and the e-mail sent by you to your clients through your ISP or through your MLS vendor or lead generation company you have hired, may not be getting delivered to the intended recipient. Many ISPs (and AOL) block e-mail for many different reasons and in many cases for very little reason (and they block LOTS of e-mail). They are setting up filters and gateways to block spam and anything they think has the slightest "appearance" of spam.
Why? Not only is spam an irritant to you, filling your Inbox each day and taking up your time as it downloads, spam is also choking the Internet providers.
You think you have problems with spam. Internet providers not only have their resources used in the delivery of spam (which costs them and ultimately costs you), they are often black listed because of new methods of spamming which turn innocent computer owners into spam generating zombies. Black listing causes the e-mail of all their clients to be blocked...not a good situation for an Internet provider.
Is there a way to increase the flow of legitimate e-mail and decrease the spam?
Yes. Implementation of simple standards (known as RFCs) can improve the current flow of legitimate e-mail.
NOTE: RFC is an acronym for “Requests for Comments” which is a set of technical and organizational notes about the Internet (originally the ARPANET). Memos in the RFC series discuss many aspects of computer networking, including Internet protocols, procedures, programs, and concepts, as well as meeting notes, opinions. For more information on the history of the RFC series, go to ftp://ftp.rfc-editor.org/in-notes/rfc2555.txt
The official specification documents of the Internet Protocol suite that are defined by the Internet Engineering Task Force (IETF) and the Internet Engineering Steering Group (IESG) are recorded and published as “standards track RFCs”.
Another solution for AEs who are not receiving all of their e-mail is to discuss blocked mail with their ISP, which may help or it may get them nowhere as technology as companies always like to blame "the other guy." At InternetCrusade we refer to this as the "Chain of blame."
America Online blocks some half billion pieces a day. In everyone's attempts to reduce the flow of SPAM, filtering is taking place to the detriment of all those who want to continue to use e-mail as an effective business communication tool.
ISPs and other email carriers have been frantically reviewing their rules regarding accepting email. E-mail may be blocked (rejected) if:
1. The message being sent exceeds limits set by the recipients ISP
2. The message being sent has too many addressees in the address fields (To, Cc, Bcc)
3. The message is being sent to an AOL user (we need to move REALTORS away from AOL as their business communication manager).
4. The recipient has attempted to utilize spam filtering software and "good" e-mail is being filtered
5. The recipient has included certain word blocks, which can block otherwise good e-mail (I once had an e-mail blocked because the word Middlesex was in the subject line)
6. Standards are not being adhered to by e-mail providers who do not really understand e-mail. Prior to the days of SPAM, it was not as important for e-mail providers to know all the required e-mail standards. All e-mail was delivered. Today, if certain standards are not met, e-mail may be blocked by legitimate e-mail providers. "Good" e-mail is being blocked because to the intended recipients e-mail provider, the e-mail being blocked "looks" like SPAM (identified as such because of information in the header of the e-mail that has the characteristics of SPAM).
Certain ISPs only accept email from servers that comply with certain standards (such as RFCs mentioned above).
Some well known MLS vendors, Web hosts, e-mail marketing companies and lead generation web sites do not comply, and as a result, lots of legitimate email (false positives) is being rejected.
In addition, a simple group of tests called SAV (senders address
verification) are also being used by major ISPs and mail handlers.
SAV (senders address verification) is "call back to sender" which attempts to verify if the sender is legitimate before accepting the email. This stops the forgery of senders addresses (what most spammers attempt to do).
Detecting the rejection of legitimate mail is made difficult because:
1. The recipient, don't know it's being rejected.
2. The administrator of the "sending service", (MLS, web servers, etc), is not informing you, their client, that email for you is being rejected.
3. Some vendors deny the situation even exists, BUT IT DOES EXIST.
At InternetCrusade, we work with vendors (as much as they will allow us) to help them solve their issues.
InternetCrusade has a system in place that allows us to trace and track each attempted email delivery so we can prove to vendors (and our customers) what the issues are in the first instance.
For over 10 years, email has been a core product for InternetCrusade and we have been delivering email (primarily to the real estate industry).
InternetCrusade’s Vice President of Technology, Mike Barnett suggests the following "best practices" which assure that mail will be delivered with the fewest difficulties for ISPs. Please pass along this technical information to those responsible for your e-mail system:
DNS:
1. The web server must have a fully qualified hostname, like label.domain.com which has an A record.
label.domain.com. A ip.ad.re.ss
and the webserver should not be just domain.com, but label.domain.com.
2. the IP of the webserver should have a PTR hostname, label.domain.com ...
ss.re.ad.ip.in-addr.arpa. PTR hostname.domain.com.
3. ... whose A record should own that IP:
hostname.domain.com. A ip.ad.re.ss
In SMTP:
4. the webserver's Helo hostname must have a fully qualified domain name, label.domain.com, that ideally is the same as the PTR hostname (but not
required)
HELO label.domain.com.
... which itself must have a A record
label.domain.com. A ip.ad.re.ss
5. the envelope sender address used by the emailing web application ...
MAIL FROM:
... must accept _inbound_ mail at the MX machine for sender.domain (sender address verification). And it should not use a "null sender" or "nobody@"
or "www@" or "web@" or "apache@" or other default/generic name, but something self-explanatory like :
MAIL FROM:
MAIL FROM:
MAIL FROM:
... meaning that if anybody, like postfix's sender address verification function, tried to send mail back TO: complaint_form@domain.com, the MX (mail server) for domain.com would accept it.
6. The above sender domain doesn't have to be, and probably should not be, sender@label.domain.com but just sender@domain.com. If it were sender@label.domain.com, there would have to be an MX record and mail domain setup for label.domain.com, which is usually not what the client needs or wants.
7. the MX for domain.com must accept mail for abuse@domain.com and postmaster@domain.com and that msg but be delivered to a real person.
Spam Blocking Software
There are many different applications that promise to limit spam, both client side (on your computer) and server side (on your ISPs server). The problem is that none of them are perfect and they often block not only spam, but legitimate e-mail.
A false positive occurs when spam blocking software incorrectly identifies genuine email as spam. You cannot trust these applications to block only spam, and so you end up wasting time sorting through “spam folders.”
There is also the other side of the coin, the miscategorizing of spam as legitimate e-mail.
Black Lists, White Lists, and Gray Lists
Some ISPs will block all mail from servers that have the appearance of spamming activity. Blocking all mail from a server is black listing.
White listing is just the opposite, accepting mail from a server or individual regardless of the appearance of the e-mail…even if the e-mail has characteristics of spam.
Gray listing is temporarily blocking e-mail and can be quite effective in reducing spam.
If an e-mail is not accepted by the server to whom the e-mail is sent, the sending server will normally try again over periods of time and eventually give up if the e-mail cannot be delivered. It makes sense for sending servers to operate this way as there could be any of a number of reasons a single piece of e-mail is not accepted at a particular moment in time (examples: breakdown in connectivity, power interruption, filters, full mail box, etc).
Many spammers are using "zombie" computers to send spam (computers of the innocent upon whom a worm or trojan is planted for the benefit of the spammer). When these zombies generate spam, there is no allowance for undeliverable mail. If the spam is not delivered on the first attempt, the zombie will not send it again.
Now, what "gray listing" does (as opposed to white listing and black listing), is block all incoming e-mail on the first attempt. It then lets it through on the second attempt. You would be surprised at how much spam this eliminates.
What can you do about the current state of e-mail?
There are steps one can take to both eliminate large amounts of spam and have a greater assurance of delivery of one’s e-mail. It all begins with education. Don’t be afraid to have frank conversations with vendors and ISPs when you feel your e-mail is not being delivered.
