    Default Port 25

    after opening all the recommended ports on the firewall to allow traffic to the zimbra server, Port 25 does not appear to able to be accessed, (the old story where you can send email to a destination but cant receive it with a reply. )I tried telneting to the port which does not appear to be open. Other ports can be telneted to.. eg port 110. so what i did was try telnet to the port internally which does work on port 25.

    So I was thinking it had to be the firewall, but every port is set up with the same configuration. nothing different, its got me a little stumped. the zimbra.log file doesnt help me at all with SMTP connections. cant see any.

    I then tried 1:1 on the firewall, with still no luck

    the firewall is a pfsense box, using VIP just for the mail server

    any help would be grealty appreciated

    If that works internally then you have a problem with your firewall and/or NAT router (if you have one), unless you fix that there's nothing much else to advise.

    you can check setting for mta: -

    postconf -n | grep -i interfaces

    should have set for inet_interfaces=all
