Hi Victor, All mail going to virtual mailboxes seems to go to their destination excepts for tmy-main-domain.com (when i do postqueue -f )
I get this error : Jan 31 18:18:51 stock postfix/local[2203]: F011A80B6D: to=<www-d...@mail.my-main-domain.com>, relay=local, delay=278059, delays=278057/2/0/0.01, dsn=4.3.0, status=deferred (temporary failure. Command output: maildrop: Home directory owned by wrong user. ) (I just understand a very very few part of postfix and maildrop ...)
