Reg.Internal SMTP Port 26

[ithelpdesk]

Dear Friends/Support,

I have got a strange problem while setting up Proxmox and sending out emails from it.

In my Zimbra email server I am not able to set my relay host ip address port to 26 as its only allowing 25 port.But @ Proxmox when it recieves email at port 25 it swill reject saying Relay access denied.

How should I rectify this issue.

Regards,
Liju..

Make sure port 26 is open on PMG:
iptables -S | grep 26

From the Zimbra server, run:
telnet pmg 26
