Hi,
I recently experienced strange errors in mailq :
[root@numenor ~]# mailq
-Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient-------
56BF31C9391 2320 Fri Jul 18 03:42:33 [2][email protected]
(temporary failure. Command output: lda(postfix): Error:
net_connect_unix(/var/run/dovecot/stats-writer) failed: Permission
denied)
[3][email protected]
All other messages are getting in without error.
Furthermore these are probably spam which shouldn't get in, since
postfix@ is not in the authorized recipients
When it happens, it is always spam for postfix@
Any idea ?
Check your dovecot config for the permissions: Postfix user needs access
to /var/run/dovecot/stats-writer
V2.4:
service stats {
unix_listener stats-writer {
mode = 0660
user = ??
}
}
v2.3
unix_listener stats-writer {
user = ??
group = ??
mode = 0660
}
}

In an Internet failure case, the #1 suspect is a constant: DNS.
"Oh, the cruft.", egrep -v '^$|^.*#' -\_(Tu)_/- :-)

Here is the relevant part of dovecot config :
service stats {
unix_listener stats-reader {
user = $default_internal_user
group = $default_internal_user
mode = 0660
}
unix_listener stats-writer {
user = $default_internal_user
group = $default_internal_user
mode = 0660
}
}
All other mails get in without problem. I suspect it gets in, then
confuses the mail system because of proxy:unix:passwd.byname in postfix
config local_recipient_maps
I don't need this btw.
