Domino SMTP Authentication

Hi,Using Domino 8.5 server (Domino/sawag) on Windows server 2003 on Test Machine. My test domino domain is sawag. I need to know how do i set SMTP Authentication on the server.

I am connecting domino server with telnet on port 25. when it conencts i type;

helo abc.com - it is accepting and giving output

250 Domino.sawag.com Hello abc.com ([172.16.2.56]) pleased to meet you

Then i type

mail from:bogususer@bogus.com

the reply is

250 bogususer@bogus.com… Sender Ok

Now the domino should accept only the user which are authenticated from outside and/or from Domino Directory but it is accepting any user evenif i type no@no.com in place of bogususer@bogus.com

Please guide how can i configure my Domino server for the solution…

Regard,

Subject: Domino SMTP Authentication

Thanks for reply. I have applied the settings already. I have configured MS Outlook using POP3 with my Domino Server. Now when i Enable “My outgoing server (SMTP) requires authentication” option in Internet E-mail settings, it checks the users information setting properly and if the e-mail address does not match with the user’s login info, it rejects message appears on Domino console BUT if i dont enable that option “My outgoing SMTP…” it also allows me to send the message and does not check the email address i have used in User Information.

What I want to do now, Domino or Outlook should not allow the user to skip My Outgoing server requires authentication option and it does not allow the user to configre Outlook without SMTP server authentication.

Any Suggestion …??

Thanks…

Subject: SMTP Inbound Port Settings

You could modify the SMTP Inbound Port Settings so that only Name & Password authentication only is allowed (i.e. Disable anonymous), but then that may cause problems with other SMTP Hosts attempting to send email to this Server.So I think you’ll have to look for means to insure that “Name & Password Authentication Required for SMTP Host” is enabled outside of Lotus Domino; unless you can afford to disable Anonymous Authentication for the SMTP Inbound Port.
