Bug 144958

This is actually a bug in kmail. A workaround for the problem, if you have sendmail set up on your system, would be to select sendmail as the mail delivery method in KAlarm's Preferences dialog.

The KMail bug occurs when MailServiceImpl::sendMessage(..., KURL::List) is called by DCOP. The sequence of events then is:

MailServiceImpl::sendMessage():
  cWin->addAttachment( *itr, "" );
  KMComposeWin::addAttachment(KURL,QString):
    addAttach(url);
    KMComposeWin::addAttach(const KURL):
This method calls a KIO job and then returns immediately. The problem is that as soon as control returns to MailServiceImpl::sendMessage(), it calls KMComposeWin::send(1); which immediately attempts to send the message. But the KIO job still has not completed, so the attachment has not yet been added to KMComposeWin::mAtmList, and the message is sent without the attachment.
    

SVN commit 663344 by djarvie:

Fix sendMessage() DCOP call failing to wait for attachments to be downloaded
and included in the message, before sending it.

This fixes KAlarm failing to send attachments when KMail is used as the email
client. The fix will be included in KDE 3.5.7.
