Problem with Mail Server (not send & receive)

I have some problems with Mail Server. Before 1 hour I send mail normal, now I have the below message in log:

What happen?

On Rainloop:

Solved. Reinstall...

I found that your BCC configuration file overlaps with the previous parameter, let me check

When i create a BCC then i face this problem. I uninstall it and now i work without BCC.

This problem has been resolved, you can reinstall the mail server or wait for the next version update
