Issue when receiving email (all emails go into /var/vmail/Maildir file)

[asticot]

Hi all,

I experienced a problem with my ISPC3 server (3.0.4.6) which I use for emails.
I create a domain and a user mailbox for that domain.
The problem is that when I try to send an email to that new email box, all emails go to a file called /var/vmail/Maildir and not into /var/vmail/domain.com/user/...
When I look in mysql at the maildir column for that mailbox, I have the correct path (/var/vmail/domain/user)


ls -l /var/vmail
total 12
drwx------ 3 vmail vmail 4096 12 juil. 15:03 xxxxxx.com
-rw------- 1 vmail vmail 1134 12 juil. 15:03 Maildir
drwxr-x--- 3 vmail root 4096 12 juil. 15:03 mailfilters


I see no erros in mail log files.

What should I check ? Do you have any clue ?

Thank you by advance !!

Please post your postfix master.cf file. And do you use courier or dovecot as imap server?

[asticot]

In the server options, I have selected Courier as IMAP server (and Maildrop for filtering emails)

Are there any errors in your mail log (in the /var/log/ directory)?

[asticot]

There is no error in my /var/log

Here is what happened when I send an email from my test account to this test account :

Seems as if there's a problem with your MySQL server. Please restart it.

[asticot]

Thank you for your reply,

I rebooted the server so all services were restarted. But there was still a problem.

I made a manual update of ispconfig (using the script ispconfig_update) in order to refresh services's configuration. After that, everything works fine.

So I can't explain what happened. I have a backup of my old /etc/ files that I can send you if you want to explore them (up to you).
