[Solved] PostFix doesn't send or receive email

[rbtux]

please don't expect me to search to relevant infos in that file ;-)

Post me:
postconf | grep "^my"

then send an e-mail an post me the logs of the whole session:
you send an email to user@example.net

then you would grep "user@example.net" check for the correct date and you will find a message id after postfix/... : for example CF0213AB43

so you grep this messageid
grep "CF0213AB43" /var/log/main.info

et voilà you got all relevant info for this sending attempt.

I can only help you, when you provide me the essential infos...
