Hello,
I'm trying to migrate to a new setup, Debian 12 with Postfix 3.7 and
Dovecot 2.3 using virtual mailbox domains. There are no local everyone
is virtual. The first problem I'm seeing is the Postfix process is
exiting:
#systemctl status postfix
? postfix.service - Postfix Mail Transport Agent
Loaded: loaded (/lib/systemd/system/postfix.service; enabled; preset: e>
Active: active (exited) since Wed 2023-07-19 15:02:03 EDT; 4s ago
I suspect this is occurring because of this:
2023-07-19T15:19:58.474716-04:00 hostname postfix/master[41002]:
warning: process /usr/lib/postfix/sbin/smtpd pid 41013 exit status 1
A few lines earlier:
2023-07-19T15:19:57.473608-04:00 hostname postfix/proxymap[41014]:
warning: request for unapproved table: "unix:passwd.byname"
2023-07-19T15:19:57.473797-04:00 hostname postfix/proxymap[41014]:
warning: to approve this table for read-only access, list

2023-07-19T15:19:57.474399-04:00 hostname postfix/smtpd[41013]: fatal:
proxymap service is not configured for table "unix:passwd.byname"
I don't have that table listed in my proxy configuration.
I'm also getting errors when atempting to access my sql aliases.cf
configuration. That looks like this and it's looking like others:
2023-07-19T15:20:02.693395-04:00 hostname postfix/proxymap[41014]:
error: open /etc/postfix/sql/aliases.cf: Permission denied

2023-07-19T15:20:02.701021-04:00 hostname postfix/proxymap[41014]:

2023-07-19T15:20:02.701791-04:00 hostname postfix/cleanup[41032]:
warning: proxy:mysql:/etc/postfix/sql/aliases.cf lookup error for
"r...@mail.example.com"
I'm seeing issues with postfix local trying to get in to this whenever
it does it tries to send to r...@mail.example.com.
Given the above I would think anything wouldn't be working since
domains.cf can't be found then receiving any email shouldn't work,
sent a test message through and it does, if I send to a non-aliases
address i.e. r...@domain.com does not work, yet u...@domain.com goes
through just fine. Here's my master.cf file and a postconf -n output.
Here's also a permissions of /etc/postfix/sql/*.cf.
Any help appreciated.
Thanks.
Dave.
