Here's an email from a non qmailtoaster-list correspondence where I/we
were checking this very thing (it seems user and domain alias' work):
<begin email>
I'm trying to get around patching, but if my experiments don't work
that's the only option.
So, if you use an alias domain doesn't it have to be registered with a
registrar?
So here's what I've done so far which allows for a user alias, and an
alias domain:
# /home/vpopmail/bin/valias -i t...@testdomain.de testal...@testdomain.de
# /home/vpopmail/bin/valias -i t...@testdomain.de t...@testaliasdomain.de
# echo "select * from valias" | mysql -u root -p vpopmail
Enter password:
alias domain valias_line
testalias testdomain.de t...@testdomain.de
test testaliasdomain.de t...@testdomain.de
# passdb query to retrieve the password. It can return fields:
password_query = SELECT CONCAT( pw_name ,'@', pw_domain ) AS user, \
pw_passwd AS password, \
pw_dir as userdb_home, \
89 AS userdb_uid, \
89 AS userdb_gid \
FROM vpopmail vp \
LEFT JOIN valias va ON concat(vp.pw_name,'@',vp.pw_domain) =
va.valias_line \
WHERE (( va.alias = '%n' ) AND ( va.domain = '%d' )) OR (( vp.pw_name
= '%n' ) AND ( vp.pw_domain = '%d' )) \
LIMIT 1
# doveadm auth test t...@testdomain.de xxx
passdb: t...@testdomain.de auth succeeded
extra fields:
user=t...@testdomain.de
# doveadm auth test testal...@testdomain.de xxx
passdb: testal...@testdomain.de auth succeeded
extra fields:
user=t...@testdomain.de
original_user=testal...@testdomain.de
# doveadm auth test t...@testaliasdomain.de xxx
passdb: t...@testaliasdomain.de auth succeeded
extra fields:
user=t...@testdomain.de
original_user=t...@testaliasdomain.de
<end email>

Hello all
I don't know if this topic was posted before, let me refresh it. Just
to share with the list.
Dovecot with many-domains option uses sql driver as Eric warned on
point 2 of QMT install.
And that driver doesn't support authentication of alias domains by
itself.
I mean, if you have q...@maindomain.com and define an alias domain
for maindomain.com, Dovecot will not authenticate q...@aliasdomain.com
I've found some workarounds to manipulate
/etc/dovecot/dovecot-sql.conf.ext and/or patching vpopmail in
https://notes.sagredo.eu/en/qmail-notes-185/dovecot-vpopmail-auth-driver-removal-migrating-to-the-sql-driver-241.html
Meanwhile I am redefining a few alias domains as main ones in order to
keep authentication flowing.
