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