Did you post a problem in some other thread? I can't see a specific problem in this thread.

If you're using DirectAdmin and the standard exim.conf file, then by default your system does plaintext SMTP authorization for any virtual user.

You can certainly make changes to the exim.conf file to do it any way you want but teaching you how to configure exim.conf is well beyond the scope of this forum (there's been an entire book published on it).

problems we met, please help.

jeff, thx for your explaination. we still meet problems like this, not resolved.

1. There is no user name and password access request when we using SMTP of this DA mail system. How I can improve it? because others can use this smtp server to send lots of rubbish emails. really dont know what to do now.

2. Do you have aNY palmlet/Instruction in PDF for this DA using? please send me a copy if possible.

thanks a bundle in advance.

SMTP doesn't ask for passwords. It advertises that it accepts them:
Code: 
Connected to da12.namelessnet.net (4.79.140.132).
Escape character is '^]'.
220 da12.namelessnet.net ESMTP Exim 4.60 Thu, 30 Aug 2007 16:43:40 -0700

250-da12.namelessnet.net Hello of1.riv.nobaloney.net [67.112.189.217]
250-SIZE 20971520
250-PIPELINING
250-AUTH PLAIN LOGIN
250-STARTTLS
250 HELP
Then if you send it email without authentication it'll refuse to send it unless the final destination is on the same server. If the final destination IS on the same server, it accepts your email.

There are two ways to authenticate. One is if the sender uses plaintext authentication, and the other is if the sender has attempted successfully to receive email (IMAP or POP3) within the last ten minutes.

If neither of these conditions are met, then exim running on DirectAdmin, unless intentionally misconfigured, will NOT relay spam.

Post the name of the server if you'd like someone to check it.

Jeff, thanks again. Just still confused about your saying.

The 2 methods for authenciation , we are not sure how to do or operate. Could you please give some simple steps for this ? I need it urgently because we still got many spams here....

For exim file, you still not make it clear that where can i find its path? (where is it?)

Please help again.

Then your problem is not what you think it is. Your server is not sending spam but receiving spam. So authentication does not apply. Nobody needs to authenticate to send you mail.

You need to enable the RBL in exim. Search this forum for use_rbl_domains and you will get all the information you need.
 
You're right enough for me, Floyd :) .

Openvox,

The exim.conf file (it's at /etc/exim.conf) included with DirectAdmin manages the authentication automatically.

If you want SpamBlocker to block incoming spam, then copy all your domain names from /etc/virtual/domains to /etc/virtual/use_rbl_domains.

And if you're doing that, don't forget to edit exim.conf so all the references to example.com are fixed.

The readme for SpamBlocker2.x (included in DirectAdmin by default as of today) is here; the readme for SpamBlocker3-beta is here.
