I don't get all emails, which are sent out of Qt

Maybe your code is faulty.

Or maybe there was an unhandled network error.

Check with etherpeek to see if the mails were sent correctly? If so, maybe they are in the junk/spam folder.

Added after 23 minutes:

etherape works ...
they were send correctly to the server, but there is obviously no response. What's wrong?

I found the reason for the problem. The message id of the messages was everytime the same, because the Id-generator didn't work fine. He brought everytime the same ID. After some additions with qsrand and qrand the id-generator works and the mails get sent.

For future information, Linux has tcpdump plus you can strace.
