Hi,
I want to replace an old mailserver setup with postfix+dovecot. The
problem I'm facing now is, that the old system had usernames different
to the e-mail address of the user. For example:
E-Mail-Address: f...@example.com
Username: foo-example.com
I configured postfix so that it passes mails to dovecot using the
following command (master.cf):
dovecot unix - n n - - pipe
flags=DRhu user=mail-data:mail-data
argv=/usr/lib/dovecot /dovecot-lda -a $(recipient)
When dovecot now receives an e-mail from postfix it logs
dovecot: lda(mail-data): Error: User initialization failed: Namespace
'INBOX.': Home directory not set for user. Can't expand ~/ for mail
root dir in: ~/Maildir
dovecot: lda: Fatal: Invalid user settings. Refer to server log for
more information.
My dovecot-ldap configuration looks quite simple:
hosts = 192.168.0.1,192.168.0.2
dn = cn=mailadmin,dc=example,dc=com
dnpass = foo
auth_bind = yes
ldap_version = 3
base = ou=users,dc=example,dc=com
user_attrs = mailMessageStore=home
user_filter = (&(objectClass=qmailUser)(uid=%u))
pass_filter = (&(objectClass=qmailUser)(uid=%u))
I think dovecot does not know that the username is not the e-mail
address, but how can I tell him?
Furthermore we have alternative addresses here, so for example there may
be an e-mail address b...@example.com owned by foo-example.com who has
f...@example.com as primary address.
Dovecot itself (IMAP) works fine, so here it can find the correct
Maildir for the user. The difference is, that I connect using the
username instead of the e-mail address in this case.
# dovecot --version
2.2.22 (fe789d2)
# postconf -d | grep mail_version
mail_version = 3.1.0
# lsb_release -a
