Obviously, nobody there remembers how it was done before...
The dual-WAN router is one way to go, it might be also worth checking
with your current ISP account to see if there is use of a smarthost
included. This would allow mail to be sent from an IP address from which
mail would not be accepted directly. If not, depending on how important
this issue is, they might consider renting a smarthost for a minimum period.
