Help: Totally stupid on Linux mail servers...
Can anyone help, I am totally lost when it comes to mail servers and Linux. I learn by doing and since I don't know where to start it's tough for me to learn. I have several Linux boxes set up from Mandrake to RH 9.0 and a clark connect gateway on RH7.3 with Webmin installed.
I would like my RH7.3 box to download all the mail from my ISP every 5 minutes, run it through a spam filter that I can add to and edit, scan for viri and then have the home clients (OSX and Evolution) read off of that. The outgoing mail would still go SMTP to my ISP.
All I know is that if I want to send mail from the server I use sendmail, and I think to get my mail on the server I would use fetchmail. All the docs I see seem to be geared towards those who already know what they are doing. Nothing relating to those who do not have a static IP, even though I do have a dynamic IP account set up with dyndns and a domain. For now I just want to learn and try it using my regular ISP in case I really screw up I can set my clients back to normal while I work on it.
