Question are you using a db like postgresql or mysql etc
when running virtual mailboxes it is just simply a better solution
my setup is as follows
i use a django project to drive it
here are the basic's
in the dovecot.conf :
passdb {
args = /usr/local/etc/dovecot/dovecot-pgsql.conf
driver = sql
}
mail_plugins = " virtual notify replication fts fts_lucene "
service lmtp {
process_limit=1000
vsz_limit = 512m
client_limit=1
unix_listener /usr/home/postfix.local/private/dovecot-lmtp {
group = postfix
mode = 0600
user = postfix
}
}
mail_location = maildir:~/
&
# cat dovecot-pgsql.conf
driver = pgsql
connect = host=localhost port=5433 dbname=scom_billing user=pgsql
password=xxxxxxx
default_pass_scheme = PLAIN
password_query = SELECT username as user, password FROM email_users
WHERE username = '%u' and password <> 'alias' and status = True and
destination = '%u'
user_query = SELECT home, uid, gid FROM email_users WHERE username =
'%u' and password <> 'alias' and status = True and destination = '%u'
#iterate_query = SELECT user, password FROM email_users WHERE username =
'%u' and password <> 'alias' and status = True and destination = '%u'
iterate_query = SELECT "username" as user, domain FROM email_users WHERE
status = True and alias_flag = False
Happy Friday !!!

Hello,
I use postfix with dovecot as an lmtp LDA with unix users and multiple
domain names and mailboxes in Maildir format placed in domain directory
like:
/home/mainuser/homes/u...@domain.tld/Maildir
or
/home/mainuser/domains/domain2.tld/homes/u...@domain2.tld/Maildir
which have the main user as a group and u...@domain.tld/u...@domain2.tld
as owner
Postfix have
virtual_alias_maps = hash:/etc/postfix/virtual
there in virtual file there is map like:
u...@domain.tld user-dom...@domain.tld
and in /etc/passwd
there are actually 2 users with the same home dir and
same UID/GID (only the username is different)
and in postfix
mailbox_transport = lmtp:unix:private/dovecot-lmtp
The issue is that when postfix passes the email for local delivery to
dovecot lmtp it sends the username as user-domain....@serverhostname.tld
but dovecot is configured with
!include auth-system.conf.ext
can't resolve this username thus fails to deliver.
I've found a workaround in the net to use custom userdb just for lmtp
like this:
protocol lmtp {
mail_plugins = $mail_plugins sieve
userdb {
driver = passwd-file
args = username_format=%n /etc/passwd
}
}
which works but produce some warnings because there is the root user (ID
0) and actually is a dirty workaround
Is there more elegant solution??
