Domain not found Errors

Question

Hi,
I am using SJSMS 6.2 and am having some troubles with mail.
I have a few feedback forms on my website that send data to a specified email address, say [email protected] In SJSMS 6.2, I have the [email protected] auto forward any emails to about 3 other accounts in other domain (eg: [email protected], [email protected] & [email protected]). I am getting the following errors come back from the other domain:
Recipient address: [email protected]
Reason: Remote SMTP server has rejected address
Diagnostic code: smtp;554 <[email protected]>: Sender address rejected: Domain not found
Remote system: dns;maila.otherdomain.com.au (maila.otherdomain.com.au Other SMTP Gateway)
Basically it looks like it is sending out the full name of my machine ie: @hydrows.mydomain.com.au when it should just be @mydomain.com.au
Obviously my machine is hydrows.
I am using some standard perl scripts to send the mail and they use the "/usr/lib/sendmail -t -n"
bash-3.00# ./imsimta version
Sun Java(tm) System Messaging Server 6.2 (built Dec 2 2004)
libimta.so 6.2 (built 00:34:23, Dec 2 2004)
SunOS hydrows 5.10 Generic_118822-18 sun4u sparc SUNW,Sun-Fire-V250
I remember in the "old" iPlanet 4 Messgaing Server, the sendmail program was replaced with an iPlanet version and everything seemed to work ok. After reading through the Admin Manual, I followed the steps as detailed in the "Handling sendmail Clients" section (Solaris 9 and above, as I am using Solaris 10).
In there is says to change in the submit.mc file:
FEATURE ('msp')dn
to
FEATURE ('msp', 'hydrows.mydomain.com.au')dnl
My original file actually had FEATURE ('msp', '[127.0.0.0]')dnl or something similar there already. After trying both hydrows.mydomain.com.au and just mydomain.com.au, compiling and then trying to email I still get the same errors.
Any ideas?
thanks,
Rob

Well, um,
what that other site is doing is counter to RFC. but they do it anyway.
First, Messaging 6 keeps the original sendmail. we now coexist with it.
Things to check:
1. can you send mail to that site with a regular client, through your Messaging Server? If you can, it's something you're doing with Sendmail.
If you can't, then um, . . .
possibly, your ehlo announcement includes your machine name. Likely, in fact, as that's normal.
If you need to "hide" that, in your imta.cnf file, down in the channel block area, locate your tcp_local config line.
On the second line, the one starting with
tcp_daemon
add a space, then "otherdomain.com.au", like this:
tcp_daemon otherdomain.com.au
that'll change the ehlo announcement.
Oh, yes.
