sendmail config from 10.01 -> 10.20

[Kelvin Newnham]

I have a system that relays all of its non-local mail to another system for delivery. It is a simple setup, has no dns running, simply the name of the relay in the hosts file. In 10.01 I changed a couple of lines in sendmail.cf. I now have to upgrade that unit to 10.20 (or 11.0). Obviously the steps are much more complex with sendmail 8.9 - can someone give the steps to achieving exactly the same effect.

[Kofi ARTHIABAH]

Kevin: the basic configuration is not that significantly different. If you want to maintain the same set up:

1. make sure that you have your relay listed in /etc/hosts
2. make sure that in your /etc/nsswitch.conf you have the entry:
hosts: files [NOTFOUND=continue] dns
3. edit your /etc/mail/sendmail.cf and insert your relay with the DS macro.
4. make sure that the file /etc/mail/sendmail.cw contains only the localhost or the name of the server. (and NOT the domain name)
5. restart sendmail with
/sbin/init.d/sendmail stop ; /sbin/init.d/sendmail start.

viola!

I have followed the above: this is the head of a test message in the mqueue

V2
T969056361
K969056361
N1
P34330
I64/8/12831
Mhost map: lookup (usa.net): deferred
$_root@localhost

Is sendmail still looking for a nameserver?

[Kofi ARTHIABAH]

Yes Kelvin, it is trying to contact the mailserver directly... please verify the following:

0. comment out the line with Mhost in your /etc/mail/sendmail.cf file
1. if you are not using dns, please remove the /etc/resolv.conf
2. in the /etc/hosts file, make sure that the entry for your mailrelay is listed eg.

10.10.2.25 mailrelay mailrelay.domain.com

3. then verify that you have in /etc/mail/sendmail.cf the following line:

DSmailrelay

4. restart sendmail if you have not already done so.

if the above does not work... can you try the following trouble shooting:

# sendmail -bt
ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)
Enter

> =M

and post what it comes up with...

good luck

[Kelvin Newnham]

There is no Mhost record in the file

sendmail -bt
=M

Sendmail is still looking for DNS. Check your nsswitch.conf under /etc. If there isn't one, in 11.0, #cp /usr/newconfig/etc/nsswitch.files /etc

if you are NOT using DNS for name resolution. Also ensure the only uncommented lines in /etc/mail/sendmail.cw are
localhost
yourhostname
anyaliases this box may be known by.
