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.

Then upgrade your firewall.  This is certainly not a valid excuse.
