-   Hello, I have a server with sendmail and works fine, except that has open relay. How do I fix it to make smtp after pop authentication? Thanks.

-   Here is a good resource for closing sendmail from spammers:

http://www.mail-abuse.org/tsi/ar-fix.html

I would, however, simply recommend using Postfix instead (the default mail
server for Mandrake).

-   Thanks, but I don't understand postfix and I have to solve the problem quickly. Perhaps in the future I will change sendmail with postfix, but first I have to learn how to configure postfix.

I read about popauthd, and I'm going to try it. Do I have to change anything in sendmail to use popauthd?

Thanks.

-   IIRC, you shouldn't have to adjust sendmail.

-   Thanks, if I have the option promiscuous relay, should I close sendmail to stop being an open relay?

-   I have configured popauthd. How can I test if my server is still an open relay? Thanks.

-   The best way would be to use the 'Test open relay' option at
http://www.ordb.org/ . They also provide links to alot of other info on
closing and securing mail servers.
