My YunoHost server
Hardware: VPS bought online
YunoHost version: 4.3.6.3
I have access to my server : Through SSH
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : no
# lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description: Debian GNU/Linux 10 (buster)
Release: 10
Codename: buster
Description of my issue
I have noticed the mail is not reaching the Thunderbird client, no new mails appear.
After that, chececk on server but it is working.
It will stop sending and receiving.
Three days ago i did reboot the server, it did solve the problem eventually but the problem came back.
Yesterday I did reload dovecot service and the mail service cambe back eventually.
yunohost service reload doveco
Today did check the syslog tail -100f /var/log/syslog
and came to this possible error
dovecot: auth: Error: net_connect_unix(/var/run/dovecot/stats-writer) failed: Permission denied
checked online and found out this answers about dovecot error:
- Error: net_connect_unix(/var/run/dovecot/stats-writer) failed (Page 1) — iRedMail Support — iRedMail
- https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=903161
but they seem to not apply to my case, this is my server:
# ls -l /var/run/dovecot/*stat*

prw------- 1 root root 0 May 4 13:15 /var/run/dovecot/old-stats-mail

srw-rw---- 1 vmail mail 0 May 4 13:15 /var/run/dovecot/stats-writer
