[TriLUG] AOL's new email policy

[Turnpike Man]

I'm wondering kinda the same thing... a buddy of mine, who has basically has an
identical setup as myself started receiving this:

   ----- The following addresses had permanent fatal errors -----
    (reason: 550-The IP address you're using to connect to AOL is either
open to the)

   ----- Transcript of session follows -----
... while talking to mailin-03.mx.aol.com.:
<<< 550-The IP address you're using to connect to AOL is either open to
the <<< 550-free relaying of e-mail, is serving as an open proxy, or is
a dynamic <<< 550-(residential) IP address.  AOL cannot accept further
e-mail <<< 550-transactions from your server until either your server is
closed to free <<< 550-relaying/proxy, or your ISP removes your IP
address from their list of <<< 550-dynamic IP addresses. For additional
information, please visit <<< 550 http://postmaster.info.aol.com. ...
while talking to mailin-02.mx.aol.com.:
>>> QUIT


Now I have had my sendmail running on RR for 1.3 years now, he has been running
only 3 months maybe.  I have a proper domain and proper DNS and MX records
setup, as does he to my knowledge.  As far as I know, I am still able to send
and receive without issue to aol users, thus far, although generally I don't
correspond with aol users so I wouldn't really know if that helps or hurts me. 
But this right here: "or is a dynamic <<< 550-(residential) IP address".  That
really sucks if that is the case.

I too question, how will they know it is dynamic??  Well, AOL is Time Warner
which is where my RR comes from... could RR be supplying AOL with the 24.x.x.x
block as a, "this is our block dedicated to DHCP addresses so you can block all
of these right away" kinda thing??  Any ideas?   I think we have RR employee(s)
in our group do we not?  I'd love to find out.  And if my domain gets on AOL's
blacklist for any reason, I am going to want to know who I need to complain to
on a daily basis until the problem is resolved!  :)

laters,
David M.
