Sendmail problem

Stojcevski Dejan — Wed, 26 May 2004 06:18:43 GMT

Hy to all,
I think that this is a known problem but still ...
My sendmail is not working properly: When I try to send a mail outside the HP-UX 11 an error is occuring (attachment). Relay host in sendmail.cf is configured and it's hostname can be resolved (ping by histname to that server works). Still sendmail wont send the mail. It is complaining about "Service Unavailable"!
Please help !

Check if your hp-ux host is allowed to send emails to smart relay.

Do telnet smart_relay 25 from hp-ux box and check.

Hi to all,
I think I have found the solution:
In the /etc/hosts file the name of the host is as follows:
xxx.xxx.xxx.xxx host host. (WITH DOT AT THE END!)
For some reason sendmail takes the second name (the one with a dot!) and that name is not listed in the external SMTP server as a trusted host from which it can accept mails!Probably this is done because someone did not want the mail.log to be filled with the "can not qualify my own domain name" text over time!?
So this is just to watch over the same problem if it ppears in the future.
Anyway thanks to you all!
