Description Rolf Eike Beer 2011-06-12 12:57:40 UTC

Version:           1.99.0 (using KDE 4.6.4) 
OS:                Linux

If I use 2 or more mails using the same transport I see KMail opening a new SMTP connection for every mail. KMail should use the already created connection to send every mail through them which will reduce load especially for SSL/TLS encrypted connections as the SSL handshake has to be done only once.

Reproducible: Always




OS: Linux (i686) release 2.6.37-12-desktop
Compiler: gcc

I can confirm this bug.

Thank you for taking the time to file a bug report.

The compontent kdepimlibs don't exist anymore since 2011. It was splitted into several parts some moved to Frameworks the other are still under de KDE PIM umbrella. 

The entire code base went through significant changes. We ported the source code in meanwhile  to Qt5 and KF5. It is unlikely that these bugs are still valid in KMail2.

We welcome you to try out the new 20.08 release and give your feedback.
