Thanks to everyone who helped out...
I've temporarily gone to relaying my mail through my ISP's smtp server,
they wouldn't sell me a static IP address, and they wouldn't let me keep
my mailboxes only, so I might have used another ISP for dial-up access
and not tampered with email addresses. When I asked why they assign
blacklisted IP addresses, they said they no longer support dial-up
customers with their own mail servers, everything must be relayed
through them.
This seems to work fine, my first message was bounced back to me because I
didn't have authorization, but since then, outgoing mail is fine, though
I have no (client side) smtp auth in my exim.conf, and I keep expecting
to have to figure that out (I'll be back then).
One thing that puzzles me is that while my inability to transfer mail
out and the use of my machine to launch spam occurred at more or less
the same time, I don't think my messages were rejected because of being
blacklisted, because, for example, panix.com (where this message is
coming from, and to which I couldn't transfer mail) doesn't use any
blocking or filtering software. While my exim.config file remained
untouched from Sept, I still wonder if it wasn't a configuration problem
which caused the mails to fail (when I originally set up exim, I had a
lot of difficulty because my hostname contains uppercase characters, but
I eventually figured it out).
When my messages were failing, they would terminate in "connecting to
mailhost..." and then just hang until I manually killed the process. Is
this what happens when messages are rejected because of being
blacklisted? Following is a trace of a message and my old exim.conf
(prior to modification for relaying mail through my ISP, thank-you
Suresh). Just including this in case something similar happens to
someone else, no need to reply.
Thanks again,
Tomasz
