A typical one this, and a trap that I have fallen into from time to time,
so here goes ...
In the domain fulast.nu there are references to two machines that will
handle the mail, <snipped from a nslookup command>
# nslookup -type=mx fulast.nu
Server: localhost
Address: 127.0.0.1
fulast.nu preference = 20, mail exchanger = echo.dominera.se
fulast.nu preference = 10, mail exchanger = charlie.dominera.se
fulast.nu nameserver = ns1.dominera.se
echo.dominera.se internet address = 195.100.198.36
charlie.dominera.se internet address = 195.100.198.34
ns1.dominera.se internet address = 195.100.198.34
Now the most important mailserver (highest priority, lowest value) is
charlie.dominera.se so all mail will be sent there.
When mail gets to charlie, sendmail will see if it is to handle it locally
or to relay it on. Local mail domains are defined in a file called
sendmail.cw, and if not defined there then the message is assumed to
be needing a relay. But when charlie does a nslookup to find where to
send it to, it finds itself, hence the error message that you see.
Solution? Add the following line to sendmail.cw (in /etc or /etc/mail)
fulast.nu
Simple, just that line with the domain and nothing else.
Oh, you will have to update aliases or virtual users file(s) to define
the names of the users in that domain and where to send their mail.
hope this helps,
Godfrey
