After months of working on it, I finally got my masqing working with a DHCP server running. Now I want to turn it into a mail server. I have accounts for the four members of my family already on the linux box. I have accounts with my ISP for them as well. I think I have fetchmail on the system, but I don't think it is running (ps -ef | grep fetch gives nothing). I know I have an imap mail server on the system, but it too is not running. I have sendmail on the system. When I write an E-mail from within itself, it goes out fine. I tried setting up one of my Win95 PCs with the linux box as the SMTP server, but it puked with the error (using outlook Express 5 as the mail client) when I sent a test message to myself: The message could not be sent becuase one of the recipients was rejected by the server. the rejected e-mail address was 'jwaldack@kc.rr.com'. Subject 'Test', Account: 'Test Account', Server: 'mufasa', Protocol SMTP, Server Response: '550 jwaldack@kc.rr.com... relaying denied', Port: 25, Secure (SSL): No, Server Error: 550, Error Number: 0x800CCC79 mufasa is my linux box with two LAN cards (one gets IP from rr.com, the other is 192.168.1.1 to the hub where the PC I tried sending the E-mail from, also on the hub, is 192.168.1.11. mufasa is defined to it by c:\Windows\hosts file). (BTW: sending an E-mail to jwaldack@mufasa.kc.rr.com works just fine from within the LAN) Is there some place I can get additional information on fetchmail, imapd, and setting up sendmail to accept E-mail from other sources? Thanks for your help in advance. - Jesse ===
