sendmail problem

[JOHN TURNER_2]

Good morning

im having a problem with sendmail, at present i have 7 servers running sendmail, all of the configuration files look the same, although when i try and send a message to an external email address 3 of the servers send the message and the other 4 do not, can any one think of anything that could of caused this. About 2 weeks ago all of the servers were sending messages

Shalom,

If this is hpux, please post the mail.log output associated with the mail sends.

/var/adm/syslog

If its Linux, see /var/log/maillog

Possible cause:

Firewall admin decided correctly that servers should not be permitted to send email direct to the public internet. If so, they should provide an smtp relay server to get mail out the door.

DNS could be down and lookup is failing. The log data will show that.

yeah, SEP is right.

check the /etc/resolv.conf file

this is the output in the mail.lig file

nmhp03{root}=>/var/adm/syslog - tail mail.log

[Jeeshan · Accepted solution]

add a line in /etc/hosts file of nmhp03 host

nmhp03

[JOHN TURNER_2]

after i changed the /etc/hosts file as requested i re-ran the sendmail command and now get the folowing error message

Feb 10 05:18:21 nmhp03 sendmail[4202]: FAA04200: to=john.turner@acs-inc.com, ctladdr=root (0/3), delay=00:00:00, xdelay=00:00:00, mailer=relay, relay=mail-proxy, stat=Host unknown (Name server: mail-proxy: host not found)

[Jeeshan]

what is your /etc/resolv.conf entries?

and what is your relay server name?

is relay server name exist in /etc/hosts file?

[JOHN TURNER_2]

we dont have a /etc/resolv.conf file, but there is also no resolv.conf file on the servers where sendmail is working so i dont think that is causing the problem. As for the relay name, i have no idea, where abouts would that be stored as i could try and find it on the working sendmail servers

[Dennis Handly]

>As for the relay name, i have no idea

Have you compared the DS entry in sendmail.cf files?

thanks for all your help, the problem was that someone had commented out the mail proxy entry in the /etc/hosts file. I have made the necessary changes and sendmail is now working on all seven servers
