Evolution: Sending mail takes several minutes

view full story

http://askubuntu.com – When I send a mail, it takes several minutes (~20) to finish this task. I can see a status bar item, percents increasing. I wouldn't mind much; the problem is that until it's done, I can't see the mail in the Sent folder and can't work with it. This behavior started without any reconfiguration. Other users of the same mail server do not experience this trouble. How can I fix this? (HowTos)
