Description Freek de Kruijf 2022-07-19 15:16:54 UTC
SUMMARY
***
Sometimes messages with sender my gmail.com account hangs in the outbox of Local Folders
***

STEPS TO REPRODUCE
1.  Compose a message with my gmail.com address as sender
2.  Submit it for delivery
3.  It does hangs in the outbox of the Local Folders without a warning
4.  When restarting KMail somewhat later a message arrives that sending has failed because the remote host closed the connection.
5.  A workaround is to use "akonadictl stop" to kill all akonadi processes and to restart akonadi in Kmail. After that  most of the time a message appears about a DBUS something is not present or ready. This is not very important. Clicking right on the outgoing mailbox and choosing Send messages in queue makes the hanging message to be delivered.

OBSERVED RESULT
Message hannging.

EXPECTED RESULT
Messages should be delivered immediately or later automatically.

Don't really know what to say, I've got the exact same problem.
5.25.5 on archlinux.

Usually, the first mail I send works ok, at least if that's shortly after a new plasma session. But if I try to send another one after a while, this one will hang until I restart akonadi.

Is there some information that can be provided ?

Comment 3 malcolm macleod 2022-11-21 06:46:04 UTC
I have to restart akonadictl every time I want to send an email out of kmail from one of my gmail accounts. This is a usability nightmare.
Is there any info that can be given to get this resolved?

Don't cache promises for AccountManager::findAccount

Unlike AccountManager::getAccount and AccountManager::refreshTokens, this
method does not return an authenticated account. However, the promises are
cached for all of them in the same store, so it was possible for a call to
e.g. refreshTokens to get a promise created by findAccount instead, resulting
in an unexpected result. Just don't cache promises created by findAccount.

SmtpJob: Fix use of KCompositeJob

SmtpJob overrides slotResult, but this had two issues. First, it connected
to LoginJob::result itself, though addJob already does that. Second, in two
cases it did not remove finished jobs from the list of subjobs, leading to
dangling pointers and messing up state. This was most likely only reached
in the case of an expired XOAUTH2 access_token and caused the job to fail
after a successful refresh.
