So he/she can't relay via my servers using the sniffed user/pass ...

Hmm, I remember some problems with misconfigured MTAs that advertised
TLS, but then weren't able to provide it. The responsible admins blamed
us that we weren't able to send mails to them, because other servers
could send them mail... *sigh* There were quite a lot of them, so I
started using "hosts_avoid_tls = *" too.
After some time of running a medium / large mail site you start avoiding
problems wherever you can, because *lots* of the mailservers out there
are administered by people who really don't know what they're doing.
