[Eisfair] Probleme beim Mailversand

[Stefan H.]

Hallo,

bei mir ist es in letzter Zeit immer mal wieder vorgekommen, dass Mails, 
die ich gesendet habe, nicht zugestellt wurden - ohne Fehlermeldung.

Heute habe ich eher zufällig im /var/spool/exim/log/rejectlog folgendes 
gesehen:

2026-06-04 14:23:22 cram_server authenticator failed for localhost 
(www.fam-heidrich.net) [127.0.0.1]: 435 Unable to authenticate at 
present: unable to connect to UNIX socket (/run/dovecot/auth-exim):

Passend dazu gibt es in /var/spool/exim/input Dateien, die ungefähr 
folgenden Inhalt haben:

1wU08o-000000000Ar-0wa1-D

Ich versende meine Mails; hier im Beispiel über mail.gmx.net.

1. Frage: Warum bekomme ich keinen Hinweis dazu, dass die Mail nicht 
versendet wurde?
2. Frage: Hat jemand eine Idee was ich tun kann/muss?

Viele Grüße
Stefan
