I might be misunderstanding what you are trying to achieve, but it sounds to me that you need mail aliases.

Check the "alias" option of "action", and also the section "Aliasing tables" in table(5).

Hey,
first of all i want to thank you all for your work on OpenSMTPD over all those years. It has powered my one domain very well over all those years. But now i have a problem with setting up virtual domains and users.

My goal is the following. I have the following domains:

foo.com
bar.com

With those domains i have the following email addresses:

us...@foo.com
us...@foo.com
us...@bar.com
us...@bar.com

But all those users dont exist on my machine as real users. I just want to recieve emails for those accounts and process them via lmtp to dovecot. So my action basically looks like that:

action "local_lmtp_deliver" lmtp "/var/dovecot/lmtp"

But when i trace the lookup from the smtpd i get the following:

b4e62ea90ed6c91d smtp connected address=local host=foo.com
lookup: match "local" as NETADDR in table static:<anyhost> -> true lookup: match "foo.com" as DOMAIN in table static:<anydestination> -> true rule #1 matched: match from any for any action local_lmtp_deliver lookup: lookup "user1" as USERINFO in table getpwnam:<getpwnam> -> none b4e62ea90ed6c91d smtp failed-command command="RCPT TO:<us...@foo.com> " result="550 Invalid recipient: <us...@foo.com>" b4e62ea90ed6c91d smtp disconnected reason=disconnect
debug: control -> client: pipe closed
debug: clearing p=client, fd=11, pid=0

For some reason the user1 part is still getting resolved as a real user on the system. I read on the man page and found the "user username" option for the action. I did the following:

action "local_lmtp_deliver" lmtp "/var/dovecot/lmtp" rcpt-to user "dovecot-worker"
dovecot-worker is the account used by dovecot to handle all the email storage in /var/vmail. But i get the same error.

So i guess i am doing it all wrong. Could someone please be so kind and give me a hint in the right direction how the virtual user stuff is working in OpenSMTPD. Because i think i am lost here. I am doing something completely wrong.

I am on the latest OpenBSD release (including all syspatch).

Thanks so much!
Greetings
Leo
