hi suresh
thanks for the info...I was not aware of this...
I have filled in the form...
however we can see that AOL is even blocking IP's from fixed IP block, =
of
which we know, that these IPs have never been used before for sending =
mails.
we have activated some servers on those IPs for testing AOL...
so the suspicion is, that AOL is blocking whole ranges..
may be a postmaster of them is on this list....
regards
tom

Betreff: Re: AOL Mail Problem
What you have run into is called AOL's "second received line" filtering
If your adsl customer is infected, or someone who had that IP recently =
[if a
dynamic IP] is infected and his PC is originating spam and malware .. =
AOL
will block any email with that infected IP in the headers.
Simple reason for this .. a lot of malware is getting quite good at
hijacking Outlook or other MUA on a user's PC [including smtp auth
credentials if any] and sending out spam through the ISP's mail relays.
Please sign your IP space for a feedback loop from aol -
