Package: exim4 Version: 4.94-2 Severity: normal Dear Maintainer,
I'm using exim4 on a laptop to send email through a smarthost. Up to 4.93-16, everything went well. Since upgrading to 4.94 (4.94-1 and 4.94-2 display the problem), I have noticed delays when trying to send email after the laptop has been sleeping. My mail client (emacs) simply gets stuck until I cancel the message, or wait long enough. At first I thought that it simply got stuck, but while testing i noticed that the delay is exactly the time that the laptop has been sleeping. Here the laptop has been asleep 1 minute and 11 seconds: 2020-06-15 01:17:44 1jkbsm-000Stl-SK <= r...@lybrafox.be H=(sphax) [::1] P=esmtps X=TLS1.3:ECDHE_SECP256R1__RSA_PSS_RSAE_SHA256__AES_256_GCM:256 CV=no S=664 id=87y2ops0do.fsf@sphax 2020-06-15 01:18:55 1jkbsm-000Stl-SK => r...@lybrafox.be R=smarthost T=remote_smtp_smarthost H=mail2.lybrafox.be [37.59.240.190] X=TLS1.2:ECDHE_SECP256R1__RSA_SHA256__AES_256_GCM:256 CV=no DN="CN=mail2.lybrafox.be" A=plain C="250 2.0.0 Ok: queued as 394FB419A4" 2020-06-15 01:18:55 1jkbsm-000Stl-SK Completed And here it has been asleep exactly 4 minutes 2 seconds: 2020-06-15 01:51:07 1jkcP5-000V8E-MS <= r...@lybrafox.be H=(sphax) [::1] P=esmtps X=TLS1.3:ECDHE_SECP256R1__RSA_PSS_RSAE_SHA256__AES_256_GCM:256 CV=no S=664 id=875zbtqk9i.fsf@sphax 2020-06-15 01:55:09 1jkcP5-000V8E-MS => r...@lybrafox.be R=smarthost T=remote_smtp_smarthost H=mail2.lybrafox.be [37.59.240.190] X=TLS1.2:ECDHE_SECP256R1__RSA_SHA256__AES_256_GCM:256 CV=no DN="CN=mail2.lybrafox.be" A=plain C="250 2.0.0 Ok: queued as 8E27141DEE" 2020-06-15 01:55:09 1jkcP5-000V8E-MS Completed I didn't test for longer delays, but when I leave the laptop asleep for the night, my mail client just stays stuck. Restarting the exim4 service makes it work again without delay, but does not make the stuck messages get delivered. For that I need to manually kill the stuck daemons and restart the service. I reverted to 4.93 for the time being, but it's easy to get back to 4.94 if you need some testing.
