Hi,
In summary, postfix mail works fine if VPN if off, does not work if VPN
is on, any advice would be appreciated, thanks DAN
So postfix is not the issue, but vpn is. :-)
You can configure a vpn to route all traffic into the tunnel. A valid
configuration for branch offices or roadwarriors so no malware can
forward internet traffic through a vpn into a company network.
I propose to investigate further into this direction.
Groetjes
