mail requirements

[Ricky B. Nino]

Hi,

I have a SHELL script that automatically sends (mailx) email messages to centain email addresses.

These messages were not delivered succesfully. What are the things I need to consider?

Thanks...

Hi,

First look at /var/adm/syslog/mail.log file. It contains the errors.

Also look at your the mailbox of the account that is used to send mails. It may have returned mails that can give you some clues. To view the local mailbox use "elm".

$elm

Hi Guys,

To be more specific. My email recepients resides in MS-Exchange Server.

Do I need to make my Unix server recognize this server? how?

To route all your out-bound mails through an exchange server, you need to configure it as the "Smart host" in the sendmail.cf file in /etc/mail directory. The relevant part of the sendmail.cf file below.

------------------
# "Smart" relay host (may be null)
DSmydomain.foo.com
-----------------------------

Where, mydomain.foo.com is the name for your Exchange SMTP server.

Hi Michael,

Im trying to debug my system's sendmail.cf file. and it's quite complicated for me.

I encountered a line that says... "check_relay -- check hostname/address on SMTP startup". Any idea where can I locate this startup file?

Hi Ricky,

There should be no need to do any further changes to your /etc/mail/sendmail.cf file other than the changes I mentioned before.

Make the changes and then restart the sendmail process.

# /sbin/init.d/sendmail stop
# /sbin/init.d/sendmail start

Hi Michael,

It worked! thanks...

Also, I tried to enter more than 1 "Smart host". First is for Exchange Server and the second is for Unix Server. The second does not work. why?
