That "if" is rapidly becoming a *requirement*. I invite you to participate
in SPAM-L@PEACH.EASE.LSOFT.COM is you somehow feel differently.

Then make the offsite MX use a user list, or else don't use an offsite MX at
all. Sending mail exchangers will retry when the recipient servers are
down; that's mandated by SMTP. You don't need an offsite secondary MX that
has no access to a valid address list.
Sorry to burst your bubble, but as of this year, where the levels of virus
bounce spam as hreached obscene levels, this is no longer a valid excuse.
: For high-volume sites, there are also firewall state issues
Then upgrade your firewall. This is certainly not a valid excuse.
