Bug 129017

Version:            (using KDE KDE 3.5.3)
Installed from:    Gentoo Packages
Compiler:          gcc 3.4.5 
OS:                Linux

I have the following problem accessing my fastmail.fm imap account using kmail. I don't know if it is a fastmail.fm or a kmail problem.

Every now and then I log into my fastmail.fm account using the web interface and find that huge numbers of multiple copies of a particular mail, all listed in strikethrough text, are clogging up my mailbox. These are occur in addition to the legitimate copy of the same mail, which is listed in normal (not strikethrough) text. We are talking about 100s of bogus mails sometimes, all taking up real megabytes of mailbox quota.

I think this only happens when I have kmail accessing the same imap account from another machine. At any rate, this did happen today when kmail definitely was running on another machine. None of the duplicate mails showed up in kmail itself, but the webmail interface told me that a new duplicate mail was being created (at a guess) every half minute or so.

When I shut down kmail all the duplicate mails were immediately deleted and the mailbox space they took up was freed up again.
