Bug ID: 392138 Summary: First SMTP authentication fails for almost every emails Product: kmailtransport Version: 5.7.2 Platform: Archlinux Packages OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: general Assignee: kdepim-b...@kde.org Reporter: tho...@monjalon.net Target Milestone: --- Hi, I am using KMail 5.7.3 in ArchLinux. Since recently (not sure about the version number), I have some delay when sending emails. I tried enabling logs with kdebugsettings export KSMTP_SESSION_LOG=/tmp/smtp.log akonadictl restart Most of the time, the first send attempt fails: journalctl: akonadi_maildispatcher_agent[21670]: org.kde.pim.mailtransport.smtpplugin: Login started akonadi_maildispatcher_agent[21670]: org.kde.pim.ksmtp: TLS negotiation done. akonadi_maildispatcher_agent[21670]: qt.network.ssl: QSslSocket::startClientEncryption: cannot start handshake on non-plain connection akonadi_maildispatcher_agent[21670]: qt.network.ssl: QSslSocket::startClientEncryption: cannot start handshake on non-plain connection akonadi_maildispatcher_agent[21670]: org.kde.pim.ksmtp: Socket disconnected akonadi_maildispatcher_agent[21670]: org.kde.pim.mailtransport.smtpplugin: Removing session KSmtp::Session(0x55e5c5d67ca0) from the pool akonadi_maildispatcher_agent[21670]: org.kde.pim.ksmtp: Socket disconnected Session log: C: EHLO xps.localnet S: 220 smtp.fastmail.com ESMTP ready S: 220 smtp.fastmail.com ESMTP ready Notification: E-Mail Sending Failed Failed to transport messaged.
