[Dovecot] Use a different usename than the recipient address (that require a lookup)?
Hi there,
I am integrating Postfix and DoveCot, both use LDAP to look up user/email address info. My question is this: can I create a user "jsmith" to get all emails with the recipient address: dovecotdemo@domain? Because of using LDAP, I need to do a lookup to know that the user "jsmith" is getting emails for "dovecotdemo@domain", NOT "dovecotdemo" (there will be no such user).
In postfix's master.cf, I can use LDA to deliver to DoveCot, which needs to know the user name where the message should be delivered to. But I would not know that at the time because I need to do a lookup in LDAP. Does the DoveCot delivery agent have any way to allow me return a different user name after LDAP lookup?
I would not want to modify a couple of files to accomplish that, because I would have to do that for every email address created.
Thanks, Yan

Most of my users just use their usernames as their mail directories. But, I have one I had to do something like
userdb passwd-file { args = /etc/dovecot/users }
and then define in /etc/dovecot/users for that user where his maildir is.
Another option would be to use aliases in postfix.

If you use virtual domains, you could specify where the emails go using virtual_mailbox_maps.

Why?Thanks, Yan

Why?
We are using SMTP/DoveCot to deliver messages between two systems. It is best if any modification can be handled automatically, rather than manually.

If there is e.g. "mail" field that contains "dovecotdemo@domain" value, you could set for example:
user_attrs = uid=user, (other attributes) user_filter = (|(uid=%u)(mail=%u))
