AOL Bounce Error "Improperly formated From Field" 554 RLY:FA

Exchange 5.5 SP4
WinNT SP6a

This setup has been working fine for years. Now suddenly I am getting bounced email from AOL with this message:

554 RLY:FA http://postmaster.info.aol.com/errors/554rlyfa.html 

Following that link the page says the following:

EXPLANATION:

All or part of the from address contained in your message is missing or improperly formatted.

SOLUTION:

Please correct the message "From: address" sent in your SMTP transaction. The from address is typically formatted as myEmailHere@my-Domain.com. You may need to contact your ISP or server administrator for additional assistance.

For additional troubleshooting, reference the manual telnet directions. ***The message From: address is included after the DATA command. ***

(The astrix above are mine for emphasis.)

I go through the telnet commands as AOL suggests on another page and it works fine as shown below:

220-rly-ya01.mx.aol.com ESMTP mail_relay_in-ya1.9; Wed, 08 Sep 2004 22:40:37 -04

Yes, the <> are required.  So that works well. As I highligted above with the astrix I did notice that AOL specifically asks that you put a "from: myemail@mydomain.net" after the DATA command. When I DO NOT I get the following:

220-rly-xg05.mx.aol.com ESMTP mail_relay_in-xg5.5; Wed, 08 Sep 2004 22:54:55 -04

This is a test.
.
554-: (RLY:FA) http://postmaster.info.aol.com/errors/554rlyfa.html
554 TRANSACTION FAILED

This is the error that is showing up in the bounced back email.  So AOL is requiring the "from: myemail@mydomain.net" after the DATA line. Is there some reason that this is not done when the email is sent via my exchange server? Is there some setting in Exchange to do this?

Thanks for your help.

I think this is part of AOL's whole push to get SPF "Sender Policy Framework) implemented ... (http://spf.pobox.com.) ... AOL's post about it http://postmaster.aol.com/spf/details.html


I'd have to do some more research but in the meantime you may want make sure your reverse PTR record is still available ... this will cause all sorts of NDR's from big ISP's like AOL ..

You could also try creating a SMTP connector specifically for AOL ... check out this link http://www.amset.info/exchange/smtp-connector.asp

AOL now requires you to have reverse dns setup on your ip address. Just phone up your ISP and they will put it on for you.

hehe isn't that what I said? .... For general best practice you should have a reverse PTR record for your mail server or more email than just AOL will fail ...
