Version: Unbekannt (using KDE 3.4.0 Level "b" , SUSE 9.2 UNSUPPORTED) Compiler: gcc version 3.3.4 (pre 3.3.5 20040809) OS: Linux (i686) release 2.6.8-24.14-default when i'm sending mail thru kmail, temporary files (which are the smtp mail files that i've just sent) appear under ~/Mail/sent-mail/cur that don't get deleted, even though the identities in question have a "Sent" folder on the imap server. Those "zombie mails" don't appear in the message list for the local sent folder but clod up diskspace.
Thank you for taking the time to file a bug report. KMail2 was released in 2011, and the entire code base went through significant changes. We are currently in the process of porting to Qt5 and KF5. It is unlikely that these bugs are still valid in KMail2. We welcome you to try out KMail 2 with the KDE 4.14 release and give your feedback.
