If the sending (backup) server has a static IP address, you can add it
to your /etc/tcprules.d/tcp.smtp file with a record like the 127.0.0.1
record that's there. Put it after the 127. record, but before the last
one. Using the full IP address is preferable to (more secure than) a
partial address (range). This will allow open (non-authenticated) relay
from that server. You'd better be sure that it won't start spewing out
spam though. ;) It's also a slight security risk, due to IP address
spoofing.
Don't forget to
# service qmail cdb
after changing that file.

I have a problem with one server sitting on an outside site. This server in
a Fedora core 7 box, and it purpose it to house backup data. That's it. We
have setup a crontab script to send the Logwatch details via Email. This
site has a Windows 2003 Server managing the users, etc., but mail (at this
stage is with an outside ISP)
Until we bring their mail to my Qmail server, I have a problem with messages
from this backup server.
Mail messages are being rejected by our server because of chkuser. See
reason below
(reason: 511 sorry, can't find a valid MX for sender domain (#5.1.1 -
chkuser))

... while talking to colloweb.collotype.com.au.:
MAIL From:<r...@servername.sitedomain.com.au> SIZE=1863
<<< 511 sorry, can't find a valid MX for sender domain (#5.1.1 - chkuser)
554 5.0.0 Service unavailable
Is there a way we can allow the actual user through chkuser? I don't want
to allow this one at the expense of allowing others through, just this one.
I have tried aliasing the messages through the external ISP, but the same
problem occurs.
Maybe I should try and modify the Sendmail configuration on the sending
server. Not my preferred option.
