No, Tor is smarter than that: your Tor client knows the exit policies
of the Tor servers, and it picks an appropriate exit node.

If I had to pick a reason for your problem, it would be that only 2 of
the 700 currently running Tor nodes allow port 25 to exit, and these
are likely on all sorts of SMTP blacklists.
