That's a matter of doing an mx lookup, telneting to one of their gateways on port 25, and seeing if you can infer from their banners what mail system that they are running (for the inbound smtp gateways, anyway-- since there's nothing to prevent them from layering different products). Look to mailing list archives for messages sent from the various domains, and see what the headers tell you about their outbound mail path.
Example: Inbound Comcast HSI:
$ dig comcast.net mx;; ANSWER SECTION: comcast.net. 250 IN MX 5 gateway-r.comcast.net. comcast.net. 250 IN MX 5 gateway-r.comcast.net.
$ nc -vv smtp.comcast.net 25 Connection to smtp.comcast.net 25 port [tcp/smtp] succeeded! 220 comcast.net - Maillennium ESMTP/MULTIBOX sccrmhc14 #274
So, they use something claiming to be 'Maillennium'.
If you do this for AOL, you'll see some weird-looking, probably custom AOL gateway. Earthlink says something like: 'ESMTP EarthLink SMTP Server', AT&T WorldNet is also Maillennium, Verizon.net declares 'MailPass SMTP server v1.2.0', and so on.
If you really wish to probe to see if this is opensource-ish stuff with obfuscated banners, you can try fingerprinting them using smtpscan http://www.greyhats.org/outils/smtpscan/> to find out that it's really just Postfix or Sendmail hiding behind that custom 220 banner. Actually, it's the smtpscan fingerprint file is an interesting read all by itself...
I'd been happily using mod_perl2 since 1.99r12 or so. Then, right before the release of 2.0, between 2.0r3 and 2.0r5, the namespace changed http://perl.apache.org/docs/2.0/rename.html. I realize that there are good reasons for doing this (http://marc.theaimsgroup.com/?t=111135037100002&r =1&w=2), but it was still pretty painful if you hadn't had some prior warning.
In particular, the FreeBSD ports tree is still feeling some pain. Guess I just got lazy with all the dependencies handled in the ports tree.
But, now we have to flash-cut our production systems, unless someone knows how to changes things to work under both namespaces...
Let's hope the definition is broad enought

"isn't this definition so broad as to cover all of us who run a mail server?"
I certainly hope so. Anyone who runs a mail server is burdened by the costs that result from the "abuse of the commons" that Spam is.

How about procmail (for new mail) or formail (for iterating through messages in existing mailboxes) and a perl-Email-MIME-Attachment-Stripper script?
Strip (or separate and save) the attachments from a mail message.
Eeek! My slashboxes are gone in the 'Light' view. Where did they go? Will they ever be back?
/. in Lynx-- yes, that was a text-mode web browser..."
I fear I'll be telling my children, "I remember when you could view
For the moment, I'll be suffering through the non-light view.
Did anyone else notice?
I'd start by seeing what the big ISPs are using.

Maybe "they" did something right, for a change.
