Tru64 - Sendmail 8.11.1 problems

Hi all,

I'm having a problem with sendmail 8.11.1 on my Tru64 system. I'm running 5.1b with PK3 installed.

The system is in a DMZ and DNS is not running.

I configured sendmail using sysman so that it would route all email to an email system.

I cannot send email outside the system. I can telnet to the target email gateway via port 25.

The error message I get when I sue the following command is:

sendmail -v -d8.99 myemailaddress@work

getmxrr(email-gateway, droplocalhost=1)
getmxrr: res_search(email-gateway) failed (errno=0, h_errno=0)

Re: Tru64 - Sendmail 8.11.1 problems

this error goes away if "mailserverhost" is substituted with the domain(no host part) for which the nameserver returns an mx record.

Also time to read a manual... ;-)

Re: Tru64 - Sendmail 8.11.1 problems

Well, turns out that it had something to do with DNS being configured on the system.

While reading other sendmail problems in the forum it dawned on me that somehow sendmail was trying to use the mx records instead of trying to solve domain names via smtp to the mail relay.

I started sysman and un-configured DNS and then configured sendmail again making sure it was set to local.

Sendmail is now working.
