Hello, I need help getting internet mail to domain.

Setup is gw55 3 sites one groupwise system.

We connected the domains through VPN.

Everything is functional, except for one domain wich cannot receive

I figured out it is the internet adressing that is not working. The
gwia on
the primary domain should take care of this mail.

The filters look OK. I dont need MTA exceptions on the firewall, they
connected through private IP (VPN).

I can ping anything on the internet except de server with running
(from the BM on the not receiving domain).

Could this be the cause ?

What filter would I need to resolve this ?

Or am I searching in the wrong direction ? Is it a Groupwise issue ?

Thanks for helping.
