[marvin51796]

I am running sendmail 5.2 on AIX ver 4.1. the system is on a ketthealth.org domain, and i am trying to send it to me on a kmcnetwork.org domain. And i receive nothing, now if i send it to my yahoo.com account it works fine. I am looking for any help, direction, etc etc.

Are both domains on the same server (machine)? Can you send mail out from kmcnetwork.org? Do you have dns setup for kmcnetwork.org. You need an "A" record for mail.kmcnetwork.org pointing to your servers ip. Then you need an "MX" record showing that mail.kmcnetwork.org handles the mail for kmcnetwork.org. If both domains are on the same machine, you need to list kmcnetwork.org as a local domain along with ketthealth.org and add yourself to the virtusertable.

the only domain on this machine is ketthealth.com, the dns and stuff is on the kmcnetwork.org domain. this machine only needs to send email out..it can send email to the internet, but it cant send email to the kmcnetwork.org.
currently the aix box has no setting in the sendmail.cf file. and the dns is point to a local dns on the ketthealth.com domain.
