You mentioned the firewall.
Can you check if you have the firewall disabled for IPv6?
If so, can you enable it for IPv6 and check if it is now sent correctly?
By default, the mail server is set up to use down ipv4 and ipv6, so it may be trying to send by ipv6.
Ipv6 = on
Ipv6_icmp_strict = off
Ipv6_spi = on
These are the settings

Check if you also have:
SMTP_BLOCK = OFF
at CSF configuration.
If yes, message me tomorrow between 12 and 00 UTC to take a look by anydesk
SMTP_BLOCK = OFF
