For years... this bug exists for years... nothing changes. God, that's crazy.

I have the same issue with a Gmail account in Kmail 5.14.2(20.04.2) on Linux (x86_64) release 5.7.4-arch1-1

Outgoing mail server: smtp.gmail.com
Encryption: STARTTLS
Port: 587
Authentication: XOAUTH2

Some mails will be sent right away, but after a while, they just sit in the outbox.  It take a long time, but I eventually get a notification informing me that sending has failed: "Failed to transport message.  The remote host closed the connection."

I believe this is a problem with Kmail or the mail transport agent since the mails get sent right away after a reboot.  I tried to kill the akonadi_maildispatcher_agent process, but even if it re-spawns automatically, sending the queued messages doesn't work.
