mails sent but they get lost

[Ruben Cardenal]

Hi,

I'm setting up somo machines to send all logs to another where they will be read. In one of those machines, i have a problem with sendmail:

root@grecopr1:/etc/mail# echo Hola | mail logs@grecopr2
root@grecopr1:/etc/mail# tail -2 /var/adm/syslog/mail.log
Feb 5 12:21:59 grecopr1 sendmail[24185]: MAA24185: from=root, size=6, class=0, pri=30006, nrcpts=1, msgid=<200202051121.MAA24185@grecopr1.>, relay=root@localhost
Feb 5 12:21:59 grecopr1 sendmail[24187]: MAA24185: to=logs@grecopr2, ctladdr=root (0/3), delay=00:00:00, xdelay=00:00:00, mailer=local, stat=Sent
root@grecopr1:/etc/mail#

The mail seems to have been sent, but the message doesn't arrive. This is all my sendmail minimal configuration related information:

root@grecopr1:/etc/mail# cat /etc/nsswitch.conf
#
# /etc/nsswitch.files:

root@grecopr1:/etc/mail# cat sendmail.cw
localhost
grecopr1
grecopr1.
root@grecopr1:/etc/mail#

And these parts of /etc/mail/sendmail.cf:

Dj$w.
DH grecopr2
CL root

Can anybody help?

TIA

Hi,

Trace the rulesets being used:

/usr/lib/sendmail -d21.12 -bv logs@grecopr2

and see why it's deciding to use a local mailer. Check it's using the $H macro.

Rgds, Robin

Hi,

rewrite: ruleset 98 returns: logs < @ grecopr2 . >
rewritten as: logs < @ grecopr2 . >
-----trying rule: $+ / $* / $* / $* / $* < @ $=w . >
----- rule fails
-----trying rule: $+ / $* < @ $=w . >
----- rule fails
-----trying rule: $=L < @ $=w . >
----- rule fails
-----trying rule: $+ < @ $=w . >
-----rule matches: $# local $: $1
rewritten as: $# local $: logs
rewrite: ruleset 0 returns: $# local $: logs

would indicate that grecopr2 is defined in the w (local machine name) class. Can you now run:

/usr/lib/sendmail -d37.8
to show the "w" class being defined.

Rgds, Robin.

Hi,

Towards the end of the last output you posted, you can see:

setclass(w, [192.168.136.1])
setclass(w, grecopr2)
setclass(w, [10.15.8.21])
setclass(w, [127.0.0.1])
setclass(w, [10.15.7.29])
setclass(w, grecopkg)
setclass(w, grecopr1.)

These look like additional interfaces on the grecopr1 server. At a guess, I'd say 192.168.132.1 is resolving to grecopr2, which is why it being delivered locally. Is grecopr2 a different server?

Have you checked the "logs" mailbox locally?

Rgds, Robin.

Yes, in /etc/hosts that IP was defined too as the first IP related to localhost that appears in the file. I have removed it and all works fine now. Thanks :)
