           Summary: Kmail +smtp incorrectly reports large emails unsent;
                    sends them multiple times. Crashes on close.
           Product: kmail
           Version: SVN trunk (KDE 4)
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs kde org
        ReportedBy: mstarkey wcsgabon org


In recent builds of kde4, kmail blocks at around 90% on sending large (5-6Mb) 
messages via smtp. A dialogue pops up saying Mail not sent (Malformed address) 
and asks whether to continue or abort sending messages. However, the email IS 
sent, and since I try again, the recipient receives it multiple times. The 
cancel button won't stop the sending so have to close kmail, at which point it 
crashes (see backtrace below). This may be two different bugs, but I've been 
getting it repeatly for the last week, so wanted to report. The backtrace is 
from a build this morning of 827073.
