It's always dns.

Heute brauchte Logwatch länger als die üblichen paar Sekunden, um mir eine Auswertung aufzubereiten. Erheblich länger. Ich bin dann mal auf Recherche gegangen und siehe da: Im STRACE konnte ich sehen, dass es generell viele Versuche gab, IP-Adressen auf Hostnamen zu mappen (und wieder zurück).

Tja, und mit genügend krude konfigurierten Hostnames und IP-Kombinationen wird der Prozess halt teilweise bis zum Timeout pro Auflösung in die Länge gezogen.

Ok, #exim can email me again. Just had to clear its retry database because it gave up sending everything. Guess it took a while for it to be able to run again even after clearing it, maybe #Mailjet or #Microsoft blocked me for a time, not sure. If you run into this, make sure you don't have #logwatch emailing you at the server's local mailbox and a remote mailbox in the cron.daily file for it at the same time, then clear the retry queue for #exim4. Then wait a few hours.

I've finally gotten emails to be sent from my server to myself via #exim4, a smarthost configuration, and #swaks. This page worked for me on #Mailjet, but Outlook is moving my emails to junk. I've said it's not junk, but it hasn't caught on yet. Did have to have logwatch's cron.daily thing run swaks since I can't seem to get #logwatch to email myself with my own email address properly. I had to think a lot on what to do, but this link should mostly help.

@rolle

Why not run #Logwatch? You can set it up to email you a precis of your log files every morning. So easy to keep an eye on disk use and spot threats.

Runs on amd64 & arm64 Linux Systems.

@me take a look at #logwatch. I have set it up to send a daily mail. It's quite configurable, but also works well out of the box.
Mir ist völlig unklar, wie ich zuvor ohne #LogWatch existieren konnte!
Endlich #LogWatch auf dem Matrix-Server installiert. Installation ist eigentlich kein Ding und ist auch sehr nützlich, aber ich stehe traditionell mit der Config von #Postfix auf dem Kriegsfuss. Gestern Nacht fast verzweifelt und auf Posteo geflucht, heute Morgen war's erstaunlich trivial.

¯\_(ツ)_/¯
