Hello, I am building a web server with RedHat 9.0. I am using Sendmail for the mail server. I was wondering how you setup authentication to send mail through the server? Someone told me that it's not worth letting customers send e-mail through my server and that I should only give them POP3 access because if I allow my server to be a mail relay server then I will become a relay server for spam. I do not think that this would happen if I setup SMTP authentication for people to send mail through my server. I would very much like to be able to send mail through my server and not have to worry about showing up on a spam server blacklist. I'm a newbie with linux so please explain thoroughly.
Originally posted by yourwebshop You might want to reconsider running a mailserver if you don't know anything about the MTA you will be using.
Well, how is anyone supposed to learn how to use and configure their MTA if they never build a mail server? Also, this server I am messing with is in a test environment until I can learn how to use sendmail, proftpd, BIND, etc... I also have disallowed any relaying until I figure the issue out. I am trying to take a careful approach to learning all I need to know before I put the server at risk of spam relaying and other abuses or attacks.
Thanks for the links, I will look through them and post again if I have anymore questions.
