Sendmail Configuration with SMTP Authentication

sushantchawla2005 · 06-18-2009, 05:47 AM

Hi Everybody

I have configured sendmail server for my network & bought a domain. The sendmail server is the only mail server in my network & it is working fine.

What I require is to configure my mail server so that it take username & password at the client side to send the mails by using my mail server, so that no unauthenticated user can use my mail server to send mail to anybody which can result in my mail server being blacklisted on the internet.

I am using LDAP for users central authentication.

Pllllllzzzzzzzzzzzzz helpppp

Hi Eric

Thanks for the links. Through these links I have managed to get the SSL or TLS working but still I m unable to configure my sendmail to force the users for authentication when sending mails.

Please help me regarding the above. Any help will be highly appreciated.

Hi,

First I'll need to know which manual you followed, i.c. if you configured SASL as the authentication daemon. If you configured SASL then normally you're using the shadow file to authenticate against, meaning that your users MUST exist on the Linux box. If configured another daemon let me know which.

Kind regards,

Eric

My users are getting authenticated through different LDAP Server. I was able to understand howtoforge documentation. But they have configured all this through source & I am installing all this through RPM so a bit different.

My mail server is running on SSL now but one thing left is SASL2 configuration for users authentication.

Please reply me ASAP.

Thanks :-)

Hello,

I don't have a lot of experience with LDAP and only can look into it this weekend. Meanwhile I've found these links that might shed some light in the darkness

clear and straightforward
Usefull info if debugging

If you can get it working let me know please. I'll check again this weekend and if you couldn't get it to work I'll see if there's something I can do.

Kind regards,

Eric
