i have a mail server on Redhat 9.0 using sendmail. it's working fine but i want to implement smtp authentication on it. Do i have to recompile sendmail sendmail on it. i am using the 8.12.8(default) version which comes with Redhat 9.0. plz help

Thanx

RedHat 9 should have SMTP authentication setup already. From the machine in question run:

telnet localhost 25

It will then respond with an SMTP banner. Type:

EHLO world

And look for something that says something similar to:

250- AUTH GSSAPI LOGIN PLAIN

This shows that you have SMTP authentication setup and turned on.

Best,

Samuel

it doesn't show there the AUTH ..... keyword. what i have to do to enable it? it shows SASL and STARTTLS when i do sendmail -d0.

Thanx

Edit /etc/mail/sendmail.mc and put the following at the bottom (but just before the MAILER lines):

Ensure to cut and paste that. There are `s and 's, so be careful. Then run:

(cd /etc/mail && make sendmail.cf) &&
/sbin/service sendmail restart

Then repeat my post above, and you should see SMTP auth setup on there.

Best,

Samuel
