Or are you suggesting that on multi-homes systems that SMTP clients
should use the EHLO name appropriate to the interface which is used to
connect to the server?

If you do want to do this with sendmail. the "j" macro holds the EHLO
name, and it can be set dynamically during the SMTP transaction.  This
can be useful for virtual hosting.

However, just because a host is multi-homed doesn't mean it has to use
all its addresses for SMTP.  With sendmail you can specify the IP
address to be used in client mode:

          O ClientPortOptions=Family=inet, Address=10.0.0.1

Similarly, the EHLO name can be specified statically as the "j" macro:

                       Djehlo-name.example.org
