Don't even need a mail log:

Try this:

sendmail -v -d8 -d38 rauthanms.external@infineon.com

type
.


The relay server needs to permit relay from your server.

This is defined in the file /etc/mail/access

ip_address_of this machine RELAY
#example
192.168.0.30 RELAY

This is done on the machine you are trying to relay through.

You would then need to build the access.db file using one of the methods given on http://www.sendmail.org

I'm assuming relay is set up in the sendmail.cf file.

Its possible to set up these options in sendmail.mc, making it easier to understand and manage options. The same database building script from sendmail.org (my enhanced anti-spam version attached) will handle things for you.

I was wrong btw,the log does help.

Nov 25 10:44:00 mscim12 sendmail[8477]: gethostbyaddr(10.10.10.12) failed

Shows a possible DNS lookup problem. Maybe the user made a mistake, maybe the /etc/resolv.conf servers aren't getting good data.

I still think the relay setup is at fault here.

relay=appmail.mkz.infineon.com, stat=Deferred: Connection reset by appmail.mkz.infineon.com

This server is rejecting relays. That is what needs to be done.

You can follow the guides at sendmail.org or what I've posted but I believe the relay server is not set up properly. DNS may be a contributing factor.
