Hello,

I am pretty sure this is not an exim issue. Either there is a local
configuration issue (e.g. an incorrect line in /etc/hosts:
IP_address alias canonical_hostname
instead of
IP_address canonical_hostname alias) or monit is sending invalid
mails, using the unqualified hostname in the notification mails.

If the latter is the cause monit should probably just use "From:
monit" and let the local MTA qualify the mail correctly.
