WARNING: Long post, has lots of debug info
+=============================================+

Hi from a frustrated sendmail user...

I have had a frustrating problem haunt me for weeks now.

The problem can be seen below.  Comments have been added between the
lines
in the debug output

First run the command to give the output...

   /usr/lib/sendmail -v -q

Output...

   Running QAA07616 (sequence 2 of 2)
   ... Connecting to mail.guestmail.net. via esmtp...

   5 Apr 2000 07:51:26 +0800 (CST)
   >>> EHLO netserv.my_domain.au

First question, why does my EHLO reply give "netserv.my_domain"
when the server is set up as "mail.my_domain"?

   250-mail.guestmail.net Hello my_domain [link_IP_address]
   (may be forged), pleased to meet you

Second question, why does my "MAIL From" show SIZE=185 rather than the
origen?

   ... Deferred: 451 ... Sender domain must resolve
   Closing connection to mail.guestmail.net.

Some tests that have been done:
-------------------------------

Our link IP address (The firewall gateway) has a reverse lookup set
on an external DNS (ISP) for the link address.  The reverse
name is "my_domain".  This does not seem to work.

I have had the ISP set it to "mail.my_domain" and changed
"MASQUERADE_AS(`my_domain') to "MASQUERADE_AS(`mail.my_domain')

With "MASQUERADE_AS(`mail.my_domain'), mail will send to domains that
do otherwise not work.  However we can not receive mail or send mail
to other domains than the ones that do reverse lookup.


The DNS entries.

109                  IN     PTR    netserv.my_domain.


What can I do to get my mail system working.  Note that all mail arrives

via port forwarding to an internal server (Netserv) and sends mail out
via
MASQ firewall.

Also note that the "mail.my_domain" IP 192.168.200.107 is a 'virtual' IP

on "eth0" on the server (The main IP is 192.168.200.109).


Is there a problem using virtual IP addresses on the server.  Do I need
to
add "mail.my_domain" to "/etc/hosts" (It is in the DNS)?

Any help would be welcommed, I am out of ideas...


Best regards
Anthony
