How to solve maildrop problem in ispmanager?

Question

linux

When delivering a letter to a local user, the following error occurs:
Mar 27 17:44:46 loft8103 maildrop[11895]: Home directory owned by wrong user.
How at least to understand where he is trying to put this very mail?
I tried to add a log file parameter to maildroprc, but it seems to start later.
Tell me where to look, please.
PS I know what many people think about ISP manager and support them. But the customer needs him for some reason, and he does not intend to refuse this monster.

Answer 1

maildrop stores mail in $HOME/.maildir
or where it is specified in /etc/maildroprc
In ISPmanager, it is configured this way by default.
$HOME - path to the mailbox
/var/www/"user"/data/email/"email-domain"/"email"/.maildir
where

• "user" - the user who owns the mail domain
• "email-domain" - Email domain
• "email" - Mailbox in this domain (part before "@")

the owner of the directory must be a virtual user (virtuser_)
you can see the ratio of the user and the home directory in /etc/passwd

grep "virtuser" /etc/passwd|awk -F: '{print $1 " - " $6}'
