Would the DIT need an additional ou, such as ou=VirtualDomains,dc=example,dc=com? I can't seem to get my head around that.
I hard code the list of domains within my main.cf, with virtual_mailbox_domains, since its a small list. You could replace that static list with a call to LDAP, like: virtual_mailbox_domains = ldap:/etc/postfix/list-of-domains.cf with some kind of one off LDAP entry in your tree, but that's more trouble that I'm willing to deal with. If your list of domains changes fairly often, then that makes more since (but might incur a slight performance penalty). It could look something like: dn: ou=domainlist,dc=example,dc=com objectClass: top objectClass: organizationalUnit ou: domainlist description: custdom.com description: example.net description: example.com description: ...

I went with a flat design, which has worked well. That is: uid=jsmith@example.net,ou=people,dc=example,dc=com uid=jsmith@custdom.com,ou=people,dc=example,dc=com and cn=jsmith@example.net,ou=groups,dc=example,dc=com cn=jsmith@custdom.com,ou=groups,dc=example,dc=comSo example.com is the suffix for the whole of the hosting database and the uids and cns are fully qualified e-mail addresses? Sounds practical enough. I'll be experimenting with that starting next week.
