Acutally, this is not your SMTP file rather the section "SMTP" in
/etc/xinetd.conf.

Sure ist does in your configuration. Unlike TCPSERVER, XINETD doesnt give
you the possibility to dynamically assign IP-Addresses to the
Environment-Variable "RELAYCLIENT".

3 possible solutions:
1. Provide those IP-Adresses (to allow relay for) statically by XINETD
mechanisms (man xinetd.conf).
2. Keep your xinetd.conf settings (except for the RELAYCLIENT variable and
use Chris Johnson's RELAYCLIENT patch or my SPAMCONTROL patch.
3. Use XINETD for all Services/Daemons EXCEPT SMTP. Move to tcpserver instead.
Coexisting of XINETD and TCPSERVER is guarantueed.
