Resolved Can't receive emails

[TimoViBritannia]

Hi their,

since some days now my server can't not receive any kind of emails. In the mail log is this error:

Dec 26 12:18:51 hostname dovecot: service=lda, user=user@domain.de, ip=[]. Error: userdb lookup: connect(/var/run/dovecot/auth-userdb) failed: Permission denied (euid=30(popuser) egid=31(popuser) UNIX perms appear ok (ACL/MAC wrong?), dir owned by 0:0 mode=0755)

Could someone please help me to fix this? Thanks

I found it out. I had to add some lines to the apparmor configs as described in this page: https://support.plesk.com/hc/en-us/articles/115000064089
