Hi All,
I run a mail server with Postfix (version 2.6.6), Dovecot and Spamassassin.
The first time I saw an unexpected directory in virtual_mailbox_base
what medio dec. 2018. The mail server has been running for 5+ years.
There are more directories than the six directories I expect. I expect
one directory for each of the domains that the mail server handles.
Looking at the /var/log/maillog it seems as if:
1. An user that is handled by the mail server logs in and sends a mail
to an address that is not handled by the mail server
2. The mail is queued
3. Spamassassin kicks in and scans the mail. I don't understand that as
the mail is outgoing.
Perhaps Spamassassin creates the unexpected directory as the
Spamassassin line in /var/log/maillog refers to an unexpected file, ie.
/mnt/ebs01/vmail/landplan.dk/XXX/SpamAssassin/user_prefs. By the way,
that file does not exist.
Below is my postfix configuration
[ec2-user@ec2 ~]$ postconf -n
alias_maps = hash:/etc/aliases
broken_sasl_auth_clients = yes
config_directory = /etc/postfix
debug_peer_list = 85.191.189.106

Any help would be appreciated
