Re: [SOGo] two mailservers cannot talk to each other
In the sogo inbox from domain-A i got this messages. Undelivered Mail Returned to Sender "Mail Delivery System MAILER-DAEMON@domain-A" connect to domain-B[Public-IP-B]:25: Connection timed out Soi think its a Problem with NAT in the OPNsense Firewall, not a sogo problem. The packet goes out on the public interface and cannot go back on the same interface. dmz-ip-A --> NAT --> wan-ip-A --->.

Re: [SOGo] two mailservers cannot talk to each other
you need to setup your mailserver DNS MX records correctly you have internal and external network IPs mailservers work on domain names it's a noob thing that any mailserver admin must know how to do hence why I am letting you work it out yourself but with a huge hint.yw On 27/06/2023 02:30, "Simon Wilson" (si...@simonandkate.net) wrote: The SOGo mailing list is not going to be able to help you with this question...
