chris also wrote about using g_bind_out.
my dns currently has this:
mail IN A 188.8.131.52
and customer dns's have
MX 10 mail.advwebsys.com
if i were to add 184.108.40.206 into the network config and then do g_bind_out
someone sending TO us would still see 220.127.116.11
someone receiving FROM us would see 18.104.22.168 as source ip and therefore
i'd need to change the ptr record (maintained by my colo provider to
22.214.171.124). i should not, i think, change 126.96.36.199 to 188.8.131.52 in my dns.
so i think your solution (ed) is correct in that i need to:
1. add the additional ip address
2. change the ptr to point to it
3. set g_bind_out to the new ip address
since bind_out will force writing on the new ip, i don't think the
gateway statement is necessary.
