A workaround, but not really a solution, would be to use something
that doesn't rely on 127.0.0.1 and/or the sendmail command. For PHP,
you could instruct mail factory (PEAR, if you use it) to talk to one
of the IF addresses instead of the loopback/localhost one.
Perhaps also use Jef Poskanzer's mini_sendmail
(http://www.acme.com/software/mini_sendmail/) instead of the sendmail
command ....
# mini_sendmail -h
usage:  mini_sendmail [-f<name>] [-t] [-s<server>] [-p<port>]
[-T<timeout>] [-v] [address ...]
#
... As you can see, you can specify server/IP address to connect to etc.
