[CollEc] Monit

[Düben, Christian]

There is an issue with sending e-mails via Exim. By default, Exim tries to send e-mails from @helos. With Monit this prints "<monit at helos>: Sender address rejected: need fully-qualified address" in the Exim logs. With "echo "This is message body" | mail -s "This is Subject" christian.dueben at uni-hamburg.de", it prints "<root at helos>: Sender address rejected: need fully-qualified address". Do you know how to configure Exim so that it sends e-mails from a valid address?

  But this should not have happen.

  Sure it runs exim and it can send mail. I suspect that monit will be
  able to send mail from localhost.
