Bug ID: 435354 Summary: Sending SMTP mail doesn't work Product: kmailtransport Version: unspecified Platform: openSUSE RPMs OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: general Assignee: kdepim-bugs@kde.org Reporter: jens.uhlenbr...@gmx.de Target Milestone: --- After updating my Opensuse system to Leap 15.2, kmail2 is no longer able to send emails through SMTP with popular webservices. I've checked the SMTP settings (auto-detect and as prescribed by the services) but it doesn't work. I've tried deinstalling kmailtransport and kmail2 and upgraded to the latest stable KDE version but nothing has resolved the issue so far. The connection should be STARTTLS, but also the TLS alternative doesn't work. STEPS TO REPRODUCE 1. Writing and sending mail in Kmail 2. Mail gets transferred to Outbox but nothing happens afterwards 3. For a long time nothing happens, then I get the error message "Failed to transport message. The remote host closed the connection " OBSERVED RESULT Mail cannot be sent EXPECTED RESULT Send email SOFTWARE/OS VERSIONS Linux/KDE Plasma: Opensuse Leap 15.2 KDE Plasma Version: 5.21.3 KDE Frameworks Version: 5.80.0 Qt Version: 5.15.2 kmailtransport 21.03.80 ADDITIONAL INFORMATION -- You are receiving this mail because: You are the assignee for the bug.
