Dovecot LDA (deliver) and LDAP groups

Question

I have a LDAP and a Dovecot running on my server, the Dovecot uses LDAP as userdb and authdb, postfix is using LDA (deliver) to deliver the mails to the user. Now I want to have group email addresses like group1@example.com. This group is in my ldap like this:

objectClass: extensibleObject
objectClass: groupOfUniqueNames
objectClass: top
cn: group1
uniqueMember: uid=user1,ou=people,dc=example,dc=com
uniqueMember: uid=user2,ou=people,dc=example,dc=com
(...)
mail: group1@example.com

How can I get my dovecot LDA to except emails sent to group1@example.com and then send the mail to the uniqueMembers of the group?

Thanks

Philip

Answer 1

This is not the job of Dovecot (or it's LDA). This is the job of Postfix to expand the user. And therefore there are the virtual_alias_maps that do the expanding/rewriting. Each expanded user will then get the mail as before.

You just have to set the virtual_alias_maps to get the mapping from LDAP as described here, but you probably are familiar with that as you already get your normal users from LDAP.
