Yes, but can you change your passdb? You can use any passdb that allows
specifying user=user at domain extra field
(http://wiki.dovecot.org/PasswordDatabase/ExtraFields). For example with
passwd-file (http://wiki.dovecot.org/AuthDatabase/PasswdFile):

domain1_user:{plain}pass:1000:1000::/home/domain1.com/user::user=user at domain1.com
