Indeed, all my domains are virtual alias domains, whose valid recipients are rewritten to the synthetic virtual mailbox domain "virtual.invalid", which is delivered to Dovecot. I don't use local(8) for delivery, but it would be useful if I had to support mailing lists, vacation, ... That can always be added by rewriting addresses to a "local.invalid" domain, and delivering only that domain locally. [] I am very interested in your example, and it looks like the way I want to go, even though I don't need virtual mailboxes. Thank you for sharing it. FWIW, Sieve has a notion of 'Vacation' that looks adequate, although I didn't dig into it much as it's not an issue for me. I'm impressed with the filtering capabilities so far though, and very glad to finally move that to server-side. :) > - Domains listed in virtual_alias_domains are exclusively > designated as holding only aliases to other real domains.

The use of virtual alias maps happens for all recipients, as part of mail entering the queue via cleanup(8). Not dependent on the address class. [] Ah, Ok, thanks. One less thing to be concerned about then. > Ok, I think I'm getting it now. Once I solve the lmtp problem I will > tackle making this stuff more rational.

Postfix has a notion of "final" domains, which subsumes "virtual alias", "virtual mailbox" and "local" domains. You can use any combination of these for "locally delivered" mail. I tend to keep mydestination empty. See also the null-client walk-throgh in MULTI_INSTANCE_README. [] Ok, thanks. > 2. s/virtual_maps/virtual_alias_maps/ > 3. virtual_alias_domains= Yes, or, if you prefer, make *all* the "real" domains virtual alias, and use synthetic domains for delivery. See above. [] Yeah, more homework to do. Thanks again. Doug
