sendmail problem

[Sridhar R]

Hi,

I am unable to sendmail to my local domain.



Let me tell u in a detailed manner:

Domain Name: ashokleyland.com

My server is running HP-UX 11.23

I have edited the /etc/mailsendmail.cf file and added the domain and uncommented.

My /etc/resolv.conf is:

vorap101#cat /etc/resolv.conf
domain ashokleyland.com
nameserver 10.200.221.1


And the sendmail fails with:

vorap101#echo test | sendmail -v sridhar.hp@ashokleyland.com
sridhar.hp@ashokleyland.com... Connecting to mailrelay via relay...
sridhar.hp@ashokleyland.com... Deferred: Name server: mailrelay: host name lookup failure
Closing connection to mailrelay


And the logs (/var/adm/syslog/mail.log) shows up as follows:

Apr 27 13:52:14 vorap101 sendmail[3966]: m3R8MEL03966: from=root, size=5, class=0, nrcpts=1, msgid=<200804270822.m3R8MEL03966@vorap101.ashokleyland.com>, relay=root@localhost

And the mailq output is:

vorap101#mailq

Hi Sridhar

Do you add the mail relay host in sendmail.cf file?

Which mail relay server you are using?
MS Exchange?

[Sridhar R]

Yes, i have added that.

Below is the sendmail.cf changes that i ve done.

#Dj$w.Foo.COM
Dj$w.ashokleyland.com

# "Smart" relay host (may be null)
DSmailrelay

Yes, mailrelay server is exchange.

[Jeeshan]

Hi Again

>># "Smart" relay host (may be null)
DSmailrelay

DS

Do you enable the mail relay from HP-UX permision in MS exchange server ?

[Jeeshan]

allow the HP-UX host in MS Exchange server and add the exchange server with its ip address in /etc/hosts file and also add this in DS entry in sendmail.cf file.

Example:
/etc/hosts

10.x.x.x exchange.ashokleyland.com exchange

sendmail.cf

DSexchange.ashokleyland.com

check the relay is ok

#echo test|sendmail -v sridhar.hp@ashokleyland.com

[Sridhar R]

Hi ahsan,

You mean, in other words,

Should the hosts file of the exchange server contain an entry for the HP-UX host?

Thanks!

[Jeeshan]

no

actually you must enable relay host entry in MS exchange server. and allow the HP-UX host in host relay properties.

only allow the hp-ux host.

[Jeeshan]

you can ask your windows or exchange administrator to do such enable.
