uninstall courier

[eter4]

Is this possible to do?

Ever since the upgrade to courier customers have been comlaining non stop that mail is not going out.


Any way to switch back?

Email not being sent has nothing to do with courier, which is a mail reading protocol. If you're having problems sending out email you need to check what's happening with exim.

Check the error log files: /var/log/exim_mainlog _rejectlog and _paniclog
for any errors about the problem sending out email.

There's no need to check all 3 files at all. The other 2 are a subset of exim_mainlog.
