I never thought I'd be here with an email question!

[scooke]

Since Aug 23, I just noticed, my email has not been working on my Cloudron.

Everything checks out green.

When I send a test email, I get: connect ECONNREFUSED 172.18.0.2:2525

Here is a sample of the logs... seems like there is a null file stopping things, but I don't know what to do.

I've tried restarting the mail service.

This all has started, in retrospect, since I reinstalled a new VPS on SSDNodes to move from Ubuntu 18 to 22, and then restored from my MINio backups. All that went seamlessly... except maybe for the email.

FWIW, for now I've gone and deleted that zero byte file, 1683327674148_1683327674148_0_61_UHaVbu_48_6f92c87cedc6, and it seems I can send email (before, the Send Email test thing was giving me an error), and the email logs looks quite busy, but I can't seem to receive emails. I've gone now and restarted the whole kit and kaboodle. Let's see what happens.

@scooke ah yes, that's a haraka issue that it creates 0 length queue files at times. Your fix is correct.

I have added a workaround in the next release to delete 0 length files on startup.
