But the same problem applies when adding a new domain and account. (all domains).

Did you upgrade the server from Debian 10 to Debian 11?

As the line that caused the issue should look like:

OUTGOING_IP = /etc/exim4/domains/${lookup{$sender_address_domain}dsearch{/etc/exim4/domains}}/ip

vs

OUTGOING_IP = /etc/exim4/domains/$sender_address_domain/ip

If that is true copy the original from hestiacp/exim4.conf.4.94.template at main · hestiacp/hestiacp · GitHub

And replace exim4.conf.template with it. Don’t forget to remove the # in front of the first 3 lines If it applies to your server

Yes update Debian 10 to 11.

Should this be it? ```
OUTGOING_IP = /etc/exim4/domains/$sender_address_domain/ip


or?

OUTGOING_IP = /etc/exim4/domains/${lookup{$sender_address_domain}dsearch{/etc/exim4/domains}}/ip

Because what is in the linked configuration (OUTGOING_IP = / etc / exim4 / domains / $ {lookup {$ sender_address_domain} dsearch {/ etc / exim4 / domains}} / ip) does not work.
