Hello

I am having a problem receiving mail. It reaches my server but says the user doesn't exist.

I can send mail out without ANY issues though.

The error in the e-mail is 550 5.1.1 david.gill@lkelectric.com User Unknown.

Below I included a printout of the sendmail -bv command, clipping from my maillog file, my local-host names file, and my .mc and .m4 files.

Thank You in advance.

[root@localhost ~]# sendmail -bv david.gill@lkelectric.com
david.gill@lkelectric.com... User unknown
[root@localhost ~]# sendmail -bv david.gill@lkelectric
david.gill@lkelectric... deliverable: mailer esmtp, host lkelectric, user david.gill@lkelectric

Here is part of my maillog file. What I don't get is I send this e-mail on the 30th, but I am still getting this error today... I thought it would stop attempting to send the -mail.

I have no idea what the localhost6 is, or where it came from.

I removed the MASQUERADE_AS(`lkelectric.com') line from the .mc file.
When I run sendmail -bv, I now get the david.gill@lkelectric.com is deliverable.

I am getting a new error though.
5.7.1 relaying denied.
