Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.

I need some help setting up Postfix on my Peer to Peer lan. I have a dynamic public IP of 18.104.22.168 which is monitored by a dynamic DNS service that automatically updates my zone file through Zoneedit. My router's IP address is 192.168.2.1, and the linux box is 192.168.2.103. The linux box hostname is web01.home.net. My Internet domain name is compunerdsmedia.com. I am also forwarding ports 25 and 110 on my Linksys router to 192.168.2.103.
I have modified the following items in the main.cf file but so far no mail reaches the server:
home.net should be okay within his network if it's set up that way in /etc/hosts:
It shouldn't matter if it's fully qualified....as long as hosts set it that way you can send mail to user.home.net on a local network. It'll work basically the same as an alias, or so I've seen so far.
the 127.0.0.1 is a loopback....it's set to localhost by default.
If you add another entry to /etc/hosts for your internal IP address, the system will resolve whatever hostname you put there with the internal address. This will need to be done on any machine on your local network that you want to use to email using that hostname.
My ISP doesn't block ports 25, 80, 0r 110, so that seems OK. I changed my hostname to web01.compunerdsmedia.com and then restored my backup of main.cf. Then using webmin I changed only a few settings in the General section and now mail is sitting in my linux mailbox.
No matter how I setup my Outlook Express email account I can't receive mail there. The IPOP3 service is running, so is something else I need to do to pull mail from the Linux mailbox?
Yeah,if your pop3 port is open right now,are you sure that you do have your mail in your mail folder.To check this out,you have to type cat /var/spool/mail/username.If it outputs something,then your mail folder has mail.And next,what imap server or pop3 server did you install?If you installed washington university pop3 server,did you enable pop3??
Please message me again if you have any questions.
Thanks everyone for all the suggestions. I still haven't got outlook to grab mail so I am going to recheck my network settings. I am also considering sendmail because there is more documentation in print.
Your telnet command is correct.And did you enable pop3 by doing vi /etc/rc.d/init.d/xinet.d/pop3 and change the value to enable?<--Last line.I'm sorry that I can't remember the installation path because I am away from home.You can search pop3 configuration file by rpm -ql imap-2000a.And find an output path which is the most similar to the pop3 config file.After you have changed the value,please restart it by doing /etc/rc.d/init.d/xinetd restart.I am sure this is the correct command this time!
