Postfix
The Postfix Mail Server setup that i have conducted was because i wanted to learn something new something that is essential to us. Emails.
I have search on the web for how tos and all. When i follow the How Tos to the dot, the mailing systems never worked the way it is supposed to. Finally, after searching and changing operating systems, for ex: from Ubuntu, freebsd, centos, i frose on CentOS and found a wondeful guide that actually worked on the first shot. see link to the original post.
Note: i made a mistake in the ./conf.pl of the squirrelmail setting. i did not actually put the domain name under Server > SettingsGeneral > 1. Domain, where i actually entered only the hostname rather then the domain name. so although everything worked wonderfully i kept getting funny domain url in the email fromto. example <username>@localhost.domain.com rather then <username>@domain.com.
