Strange connections in mail.log

Hi everyone.

I just started a miab server from scratch and I’m already getting following messages in mail.log:

May 19 13:56:43 imap-login: Info: Login: user=<kriz@krizdelogi.be>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=9353, TLS, session=<xG8ew41s5wB/AAAB>

Can anyone describe what these ‘connect from …’ lines mean and why they are trying to connect to my server?

Thanks

The first 4 lines are a connection to the IMAP server. Most likely, checking for new mail.

The next 6 lines are two different attempts to deliver mail to your box which have failed. The emails seemingly have failed as you do not have the user kriz@delogi.be defined.
