Sendmail in multiple domains

[Daniel Skates]

I haev an interesting issue on one of the Unix boxes we have. It is located in NZ, and as such has a .co.nz extension on the domain name. Here in Australia it is .com.au

Whenever I send a message from this server to myself (my email address is .com.au), the exchange server receives it as .co.nz, and it is undeliverable.

mail.log shows the correct addresses going out, however SMTP relay host is showing it as going to my non-existent .co.nz alter ego.

One way around it is for them to add a .co.nz entry in exchange, but not really feasible for the masses who will use this.

Am I missing something here?

This does not look like a unix issue at all. Check what address exchange resolves your email address to.

/usr/sbin/expand_alias xyz@whatever.com

If it is expanding to nothing.com instead of whatever.com, it is exchange problem. Also good to check mail.log file and logname command.

It resolves to the .co.nz address!

However, the machines in australia resolve to the .com.au address, and they use the same exchange/relay host, so I still suspect a local issue.

I've checked the /etc/mail/aliases file, and this is OK, and as far as I can tell, it is sending to the .com.au address, however a sendmail -v shows a different story...

>>> MAIL From:
250 2.1.0 root@hostname.co.nz....Sender OK
>>> RCPT To:
250 2.1.5 daniel.skates@hostname.co.nz
>>> DATA
354 Start mail input; end with .
>>> .
250 2.6.0 <200601250410.RAA21622@iceberg.lion-nathan.co.nz> Queued mail for del
ivery
daniel.skates@lion-nathan.com.au... Sent (2.6.0 <200601250410.RAA21622@iceberg.
lion-nathan.co.nz> Queued mail for delivery)

mail.log shows the .com.au address, but exchange is receiving as .co.nz!

Any further ideas here greatly appreciated.

Try setting the DM macro in sendmail.cf to yourdomain.com.au

Also have you set DM macro in sendmail.cf file?? Also how exactly you send the email?? do you explicitely use -r option on mail/mailx?? Is sendmail running with -r option??

Also nslookup on ip address and on host name on both machines for smart realy resolve to same?

[Daniel Skates]

setting DM to
DMhostname.com.au

Seems to have made no differece.

running sendmail with:
/usr/sbin/sendmail -bd -q30m && echo "sendmail"

run using sendmail, or mailx.
logname shows: root

nslookups on both hosts: OK.

[Geoff Wild]

What about setting th DS macro to be the same relay server as well?

Rgds...Geoff

[Daniel Skates]

DS macro set the same across all of our servers. Interestingly, if I set Dj$w. to .com.au extension, still goes to the wrong place. I am thinking this lies outside the sendmail config, and more around the DODGY DNS setup I have just inherited... ;-)

Ideas? Comments?

What version of sendmail?? How is aliases setting done in /etc/nsswitch.conf file?? Also how does /etc/mail/service look like??
