Send-only server: `Destination address is unknown` when sending to local domain #32

Closed usrtax closed 1 year ago

usrtax commented 1 year ago

I configured a smtp only chasquid ( with host user.tax , base on https://github.com/albertito/chasquid/issues/30 ) , I use forwardemail.net forword email to gmail for receive mail (it already works)

chasquid send to any other email ( for example iuser.link@gmail.com ) address is ok

but send to xx@user.tax will cause error :

Can't send mail - all recipients were rejected: 550 5.1.1 Destination address is unknown (user does not exist)

how to config chasquid fix this ?

What is happening

In your setup, chasquid considers user.tax as a local domain, meaning it's responsible for mails going to it.

So if you send an email to "anything@user.tax", chasquid will try to deliver it locally, and in your example, the user is unknown and fails. This is what I was referring to in this previous answer.

How to fix it

You should add aliases for the users you want to have, forwarding their emails to the right location.

In your case, if you want to forward email that is sent to "anything@user.tax" to a single account like i.user.tax@gmail.com, you put the following in /etc/chasquid/domains/user.tax/aliases:

*: i.user.tax@gmail.com

Note that is a relatively new feature (called a catch-all alias) and requires chasquid 1.10 or newer.

I hope this helps!
