Hi,
I can reproduce the bug on my system, but I think it's GNU Emacs
related:
After I put my system to sleep for 5 minutes, sending a test mail
with GNU Emacs took 5 minutes, while sending one with
"/usr/bin/bsd-mailx" was possible without the lag.
The bug bit me for 2 days, I wasn't able to send mails in the
morning---after my system was suspended during the night. A reboot
fixed the problem. Everything else I tried failed.
I'm using GNU Emacs with the Mew Mailer (package "mew-beta") on an up
to date Debian Sid system (exim 4.94-2, configured with my provider's
mail server as smarthost).
During the last 5 minute test, the logs looked normal, the other
mails stuck created something like this every 30 minutes:
"2020-06-16 13:22:18 1jl9X4-005JlN-Vw Spool file for 1jl9X4-005JlN-Vw
is locked (another process is handling this message)"
On sending a mail which becomes stuck, Mew displays "Sending in
background..." forever. After restarting GNU Emacs and Mew, I can
see the mail in the +queue folder; sending it is possible after a
system reboot.
I'm not an expert but I will try to look into the problem.
Thanks,
Toto
