Same address delivering to multiple mailboxes
This is by way of a sanity check; I believe something is not possible to do in Postfix without resorting to external code, but would be very pleased if I was proved wrong. Suppose I have a catchall delivery for a (virtual) domain into a mailbox: @domain => A I also have a couple of other addresses in the same domain delivering to their own mailboxes: p...@domain => B p...@domain => C So far so good, easy to set up and things work as expected. Now for the complication. In addition to the fully qualified addresses delivering to their own mailboxes I require a copy of this mail delivered into the catchall mailbox: p...@domain => B, A p...@domain => C, A Now, providing I'm prepared to do an address rewrite I can set this up as follows: virtual_alias_maps = hash:virtual_aliases virtual_mailbox_maps = hash:virtual_mailbox_recipients virtual_aliases: p...@domain p...@domain catch...@domain p...@domain p...@domain catch...@domain virtual_mailbox_recipients: @domain A p...@domain B p...@domain C The problem is that I don't want to see that rewrite to catch...@domain being done, because of just one more little complication. Instead of delivering to mailbox A, I want mail that would arrive there sent on to another MTA, so my configuration looks like this: virtual_alias_maps = hash:virtual_aliases virtual_mailbox_maps = hash:virtual_mailbox_recipients transport_maps = hash:transport virtual_aliases: p...@domain p...@domain catch...@domain p...@domain p...@domain catch...@domain virtual_mailbox_recipients: @domain OK p...@domain B p...@domain C transport: domain smtp:[MTA] p...@domain virtual p...@domain virtual If I allow that address rewite then mail for p...@domain or p...@domain will get sent on to the MTA with an envelope recipient address of catch...@domain rather than their original recipient address. I've tried various work arounds without success. The one that seems most natural, but which DOES NOT WORK, is the following: virtual_aliases: p...@domain @domain p...@domain p...@domain @domain p...@domain This results in mail for either address only arriving in their own mailbox. Is there another approach to this that I'm missing?

Sorry but having reread the address rewrite documentation several times, I don't understand how smtp_generic maps would help in this case. To restate the problem, I'm trying to figure out a way of doing the following deliveries: @domain => smtp:[MTA] p...@domain => B, smtp:[MTA] p...@domain => C, smtp:[MTA] (where domain is a virtual domain, B and C are virtual mailboxes and MTA is another Postfix server. I have the following configuration in place: virtual_alias_maps = hash:virtual_aliases virtual_mailbox_maps = hash:virtual_mailbox_recipients transport_maps = hash:transport virtual_aliases: p...@domain p...@domain catch...@domain p...@domain p...@domain catch...@domain virtual_mailbox_recipients: @domain OK p...@domain B p...@domain C transport: domain smtp:[MTA] p...@domain virtual p...@domain virtual I think I understand the purpose of smtp_generic_maps to do rewrite of both envelope and header addresses for smtp deliveries, but I can't see how that would help in this case. What would I have as my LHS in such a mapping? If I add the following configuration: smtp_generic_maps = hash:generic_aliases what would my generic_aliases file look like? If I have catch...@domain as my LHS then I've lost the information about which of p...@domain or p...@domain that I need to rewrite to, or am I missing the point? Alternatively I've played around with using the @domain format in the virtual_aliases and using that as the RHS of the generic_aliases file, but that results in just a single virtual mailbox delivery and nothing being sent over the smtp transport.

I have two mail servers. The first mail server acts as MX for a domain. That domain has a catchall delivery rule and a few specific addresses. Mail that doesn't match a specific address is forwarded on to the second mail server (via SMTP). Mail to any of the specific addresses is delivered into a local, per address mailbox on the first mail server, but a copy is also sent on to the second mail server so that this second mail server receives a copy of any mail sent to an address in the domain. The second mail server must see mail being delivered to the same address to which it was sent on the first mail server. Is this possible without a custom delivery agent, which is how I'm currently solving this problem?
