Question : Relaying mail using the AUTH-SMTP in Redhat 9

I am able to pop and send mail with my outlook client in clear text.

Two questions.
1 Is it possible to use sasldb2 to authenticate the pop3. Not sure the settings that I need to make at the server.

2 How to solve the problem of relaying denied.

I have configured the sendmail.mc to relay mail using  AUTH-SMTP. Created users into the sasldb2.
The mail server is behind a firewall.
When I try to send mail to the server for relaying from the internet I get an error
relaying is denied.

Answer : Relaying mail using the AUTH-SMTP in Redhat 9

From what I can see, the test1 account and the server config are now consistant and SNTP AUTH should work. From the maillog in the last comment it looks like AUTH wasn't tried because the mail server allowed the connection as a result of an access map or DNS lookup provision.  To tell if AUTH worked with that client it would be necessary test from a client whose relayed message is known to fail without AUTH.

Trying to test authentication to SMTP can't be done on the command line when telneting to the mail server. You can't simply enter the login name and password. That data and some other stuff must be in a bas64 encoded packet set to the Sendmail server. See  http://sendmail.org/~ca/email/authrealms.html#authexamples for examples of that exchange.
