Redmine

hi there,

some three weeks ago I installed redmine.
every thing worked as expected.

after some days redmine stopped to send notification emails.
while looking for the reason I noticed that in the log file no entries ar found for some two weeks now.
I think that these two facts are related.

What could be the reason for that?
I did install postfix in the time frame in which redmine stopped to send emails. I can imagine that there is a connection. However I fail to see it.

thanks for any help
robert

This is what mail configuration I use.
tellnetting into mail.redcor.net port 25 works fine.

production:
  delivery_method: :smtp
  smtp_settings:
    address: mail.redcor.net
    port: 25
    domain: redcor.net
    authentication: :login
    user_name: "yyy@....." 
    password: "XXXX"
