How can I find out what MTA a debian machine is using?

[stan <stanb@awod.com>]

I needed to look at my MTA log file on one of my machines today. All the
info in /var/log/mail* seemd to pertain to fetchmail, whic this machien
uses to obtain mail from upstream ISP's.

I remeber back when I configured the machien in question, I set it up to
realay all mail through one of the ISP's.

Thinking that this should be simple, I looked in /etc/alternatives, but I
did not see anything that looke liek a reference to an MTA there.

Where else do I need to look? Might this be configured on a per user
bassis? I don't think I did that.

See what happens when things "jsut worK', I forget _how_ they work. Mostly
this is "a good thing (tm)".
