Hi,
I have a java application that send out email periodically.
The application is running on a fedora 1 apache server, recently the server was put behind a DMZ.
Before the move the java application had no issues emailing, now I am getting this error
.SmtpException: 554 <127.0.0.1>: Helo command rejected: You are not me
I've looked at reconfiguring sendmail but I'm not sure this is the issue.
I've requested sendmail to accept on all addresses
DAEMON_OPTIONS(`Port=smtp,Name=MTA’)dnl
compiled with make
and restarted sendmail
no change in the result of the java application though

thanks for the help

Hmmm... you're server when connecting to the mail server isn't reporting its correct IP when sending the HELO command.
Check your etc/hosts file for correct hostname entries... or you could use system-config-network to setup your hostname.
