Hi,

I have a couple of people sending email into our system that get the following error:

email 1:
Hi. This is the qmail-send program at smtp3.electric.net.
I'm afraid I wasn't able to deliver your message to the following addresses.
Thisis a permanent error; I've given up. Sorry it didn't work out.

:
Connected to but sender was rejected.
Remote host said: 553 ... Access denied,name wcb.bc.ca
unknown to DNS

I have research, as best I can, for error code 503, but all I can find is something about check_mail, which our email host says is not activated on our system.

Can anybody give me some idea of where to start?

Thanks

Rob

From the Internet Mail FAQ:

Subject: 06.11 Fixing "post: problem initializing server; [RPLY] 553 Local configuration error, hostname not recognized as local
From: "Matthew V. J. Whalen"

Change your "mts" in "conf/MH" from "sendmail/smtp" to just
"sendmail."

From: Bill Wohler

The solution above will keep MH from using any SMTP server on your
network. require sendmail to be installed on all machines. You could
take advantage of the "sendmail/smtp" option to have MH talk to a
non-local sendmail. In $MHLIB/mts.conf (mtstailor) add:

servers

It may also be caused by old versions of sendmail.

It looks like one of the mailservers isn't configured correctly either on your end or on their end....
