It sounds like most of your problems with AOL blocking you because
of spammers or viruses could be stopped by setting up a spf (TXT)
dns record for your domain or the domains that you are in charge
of. AOL pays attention to these and will drop any mail that comes
from an IP that you do not put in the record.
Ok. I give. What in the heck is an spf (TXT) record? Something that
just came out this year? I have everything that AOL requires now.
If that is a new term for a PTR or reverse record, then I already have it.

Another problem that I have noticed with implementing this
is that a lot of hosting providers tell their customers to use their
ISP for their outgoing email because it would normally be faster. We
have several customers of ours that have connection issues between
themselves and the our server that is hosting their sites. Not
because of anything on our end, but because they are, usually, in
another country on a crappy dialup ISP. If everybody implemented the
SPF, then these people would not be able to send out email with the
return address of their domain unless it came from the server their
domain was on.
Myself, I have several return addresses that are valid, but
have all of my email forwarded to one account to pick it up from. I
also have setup an outgoing email server for myself instead of
popping into each account. My domains are on 3 different servers and
I am not the only one on those domains, but am the only one on my
outgoing email server that I have setup in my house. I would have to
get rid of my email server and start using the servers where the
domains are at, or have to setup an email server that would allow
everybody on our domains to use so that we are all coming from the
same server that the SPF policy was setup for.
SPF sounds like a good idea, but would be hard to
enforce. Wouldn't it be easier and more beneficial to have the world
come together and implement the death penalty for spammers, hackers
(illegal hackers) and virus programmers?
