Hi guys,
Just wanted to add that I had seen this behavior before several
months back. At the time, I was running AVG anti-virus, which
includes a real-time email scanning component. Basically, what it
came down to was that there was a Tor server running it's ORPort on
either port 25 or 110 (Can't remember which right now). So,
whenever my Tor client would establish a connection to that server,
I would get a message popping up indicating that Tor was trying to
establish an SMTP or POP3 connection, whichever it was. I was
suspicious at first, of course, but ended up looking at the IP it
was indicating that Tor was connecting to, taking that IP over to
the Tor network status site (http://serifos.eecs.harvard.edu/cgi-
bin/exit.pl), and looking for the IP in question. Sure enough, it
was a Tor server, and sure enough, it was running it's ORPort on 25
or 110, whichever it was.
There is a good chance that you are experiencing something similar,
and if so you should be able to verify it the same way that I did.
Best regards,
