Bug ID: 370617 Summary: SMTP config dialog uses wrong default port Product: kmail2 Version: 5.3.0 Platform: Other OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: general Assignee: kdepim-bugs@kde.org Reporter: jbev_kdebugs...@refining-linux.org The SMTP configuration dialog suggests port 25 as default. This wrong. Port 25 is supposed to be the relay port, not the submission port. The correct port is 587. Many SMTP servers also accept mail submissions via port 25, but only for compatibility reasons. Some servers even block port 25 completely. Reproducible: Always -- You are receiving this mail because: You are the assignee for the bug.
