The outgoing HELO is how your virtual hosts announce themselves when
making _outbound_ connections to remote servers. I was riffing on what
Scott said about the SMTP 220 banner, which is how your SMTP service
announces itself when greeting _incoming_ connections. They are two
significantly different areas.
The HELOs reproduce the Official Host Names of your virtual hosts and
are therefore changeable. The 220, on the other hand, will always
start with X1 followed by the OHN of the IP-bound virtual host to
which the remote server has connected. In essence, the 220 is
hard-coded, since the 'X1' is in the first position after the '220' an
is seen as the host name.
