Bug#353762: kmail: KMail freezes it's GUI when sending/receiving mail
Package: kmail
Version: 4:3.5.1-1
Severity: important
KMail freezes it's GUI when sending mails or receiving new mails.
This bug is especially flustrating when KMail filters mails through
SpamAssassing, SpamBayes or ClamAV, since each mail takes secons to
complete.
Try to write a new mail to someone and check for new mails with SPAM
and Virus filtering set up. Ensure you have some new mails to download.
The mail editor will suspend for seconds (depending on the speed of your
machine).
This problem exists for years and remains unsolved. The bug is increasingly
flustrating, since filtering time increases faster than available CPU speed.
Is it possible to move the time consuming processes out of the GUI thread?
Using a separate process or a dedicated KDE service could be a better
solution than freezing the whole application. Filtering should run with a
lower priority (around 10-15) to prevent unnecessary system hog when
checking for new mail.

YES, this is a duplicate bug-report. But I think re-reporting this bug is
essential, since usability of KMail suffers badly.
