[Tfug] Any seen AOL email problems starting yesterday?

[Choprboy]

Anybody else having problems sending email to AOL users starting yesterday 
afternoon? I think I finally fixed a script here so things should go thru 
again.

It appears that they added a new filter to their MX servers that rejects mail 
as "malformed from address" depending on it's relative location within the 
email's headers... I spent a while on the phone with one of their postmasters 
(pretty nice guy, was new though and didn't know SMTP commands or filter 
details off the top of his head, but had an amusing email address @aol) and 
finally figured it out the header order dependence an hour or so later after 
many tests...

Is anybody aware of an RFC that mandates/suggests the order of email header 
fields? I've been looking at 822/2822.. but neither seem to have any explicit 
or implicit rules for ordering, just specification of the actual header 
format and fields. Is anybody else aware of ISPs that require a certain email 
header order?
