I have a DMZ box port forward mail to the internal mail server.  MDA's are quite
secure these days when properly configured.

I don't trust web servers, especially ones that run things like PHP, so I'd toss
that out on the DMZ.

I just submit myself to ORB periodically, to make sure I haven't mucked anything
up and become an Open Relay.    Then put your mailsotre on a seperate partiion
and impose quotas.  Or deliver mail to Cyrus and let it do quotas and duplicate
message suppression.

Does the VPN source from the IpCop box (can they do that?) or from the internal
network Natted over the IpCop box?  Encryption on a VPN can be a little heavy,
as can squid, but it depends on how much traffic.  Your actually running squid
on a 16Mb box?  Wow.

I'd run squid internally on a real box, and not on ipCap, but thats just me.  I
like my firewalls to be firewalls, and nothing else.
