> Hi, Hi
I would like to put a OpenSMTPD server in front of a sourcehut lists installation  (that is, a mailing list system for sourcehut). OpenSMTPD and sourcehut communicate through a lmtp unix socket. Here is my configuration (without the filter and pki parts): listen on eth0 tls pki lists.forge.mydomain.tld action sourcehut lmtp /tmp/lists.forge.mydomain-tld-lmtp.sock
try action sourcehut lmtp /tmp/lists.forge.mydomain-tld-lmtp.sock rcpt-to
match from any for domain "lists.forge.yaal.fr" action "sourcehut" Now with this configuration I only get "550 Invalid recipient" errors, which is expected because OpenSMTPD has no way to know what is a valid sourcehut list recipient.
Your config doesn't verify recipients.
How can I make OpenSMTPD just skip the recipient verification, and just forward everything to the lmtp socket?
In your case OpenSMTPD only "verifies" whether the host-part is "@rlists.forge.yaal.f" and than tries to forward it to lmtp. But lmtp additionally expects a local user for delivery. The rcpt-to parameter passes through the recipient email-address instead of a local user.
