LinuxQuestions.org - Local Sendmail Changes Domain Name for Local Submission

I have sendmail Version 8.14.7 installed on Red Hat Enterprise Linux 7. I have two different domain names associated with my single IP adddress. They are listed in the /etc/hosts file and in the /etc/mail/local-host-names file. Incoming mail from the Internet to different @domain.com names gets delivered properly through the use of the /etc/virtusertable however, mail submitted locally on the server via command line or via PHP scripts is having a problem. Mail submitted this way to domain2.com is always being changed to domain1.com and not getting delivered. I've read that this is controlled by submit.mc, but I just can't seem to configure to accept mail for either domain, just domain1.com. Here's an example from the mail log:

Code:

Oct  3 14:13:28 HOSTNAME sendmail[32212]: x93LDRK0032212: to=user12@domain2.org, ctladdr=rsvp (1000/1000), delay=00:00:01, xdelay=00:00:01, mailer=relay, pri=30225, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (x93LDRlc032213 Message accepted for delivery)

Oct  3 14:13:28 HOSTNAME sendmail[32214]: x93LDRlc032213: to=<user12@domain1.com>, ctladdr=<user@domain1.com> (1003/1003), delay=00:00:00, xdelay=00:00:00, mailer=local, pri=30667, dsn=2.0.0, stat=Sent

Below is my submit.mc file (which, I understand, is used for local submission?):

I notice my submit.mc says 2001-2003. Did I somehow manage to replace my submit.mc file with an incorrect version? Does anyone have an example of a working submit.mc file?

Would appreciate any help anyone can provide.

Thanks,
