Everything seemed to be fine - I was sending emails OK - until this morning it refused to leave the outbox.

I thought it might be a gmail problem, but it also doesn't work with my other account mimuw.edu.pl.

I opened kmail in the console to see what error messages it might be giving, tried to send a mail in the outbox and this is what I got.

john@john-asus:~$ kmail
