I have several Ubuntu machines at work. They are all relatively current as
far as updates. We are making some changes in our domain, and I need to
reconfigure the MTA on these machiens. How can I figure out which of the
several possible MTA's are installed on each amchine?

Once I know that, it;s just dpkg-reconfigure <pakcage name> to reconfigure
tor fowarding, domain name chabges etc. right?

You can issue the following command to know which program is listening
on the default smtp port (well...it'll show other numbers with 25 on
them too): netstat -tlnp | grep -i 25


No...dpkg-reconfigure just do the basics.

Regards.

I would think they'd all have a binary named 'sendmail'. Under that
assumption:

dpkg --search `which sendmail`

Probably, but I don't recall the level of detail that gives you. With postifx
its fairly straightforward to edit /etc/postfix/main.cf. More convoluted than
that with the package named Sendmail. The other's I don't know.
