[BUG] Exim problem (failed to expand “interface” option for remote_smtp transport)

[ghost]

The emails get stuck in mail queue.

Exim log:

xxxxxxxxxxx@icloud.com R = dnslookup T = remote_smtp defer (-1): failed to expand “interface” option for remote_smtp transport: failed to open /etc/exim4/domains/xxxxxxxxx.com/ip: Permission denied (euid = 109 egid = 116)

Expected behavior

Sending emails without getting stuck in the queue due to errors.

Operating system:

Debian 11

Hestia Control Panel version:

HestiaCP 1.4.11

Additional context

Fresh install.

@mikesmith500 If you have time please test the following command:

sed -i 's|OUTGOING_IP = /etc/exim4/domains/$sender_address_domain/ip|OUTGOING_IP = /etc/exim4/domains/${lookup{${lc:${domain:$h_from:}}}dsearch{/etc/exim4/domains/}}/ip|g' /etc/exim4/exim4.conf.template
systemctl restart exim4
tail -f -s0.1 /var/log/exim4/mainlog

Then send a email via webmail / domain.
