outgoing mail on port 26

[parvezk]

Is there a way I can add a second nic with port 25 as outgoing instead of 26 i have a webapplication and it refuses to work with port 26.

No, you cant add a second nic. But such problems are usually solved by using port 25 as internal port, and port 26 as external port. A firewall is then needed to redirect external mails to port 25 to proxmox port 26.
