Is mail.foo.com running an MTA?

Does the setup of the MTA, the firewall, whatever else runs on
mail.foo.com allow connections from your web1.foo.com host?

This is probably a job of the MTA running on mail.foo.com, which
should probably have the option:

	MASQUERADE_AS(`foo.com')
	MASQUERADE_DOMAIN(`foo.com')

If it doesn't already, that is.  Handling the masquerading of outgoing
email in one central place (the MTA setup of mail.foo.com) is much
preferable, since you only have to update ONE place whenever you feel
like changing the MASQUERADE_AS option.
