could someone point me to a "How To" !!! for setting up a mail server using redhat 9, postfix and squirrelmail.

This is my first attempt at setting up a web server. Everything is working fine!!! Apache, MySql, DNS, Bind, perl, php ftp(some adjustments still needed here ), shopping carts, BBs, phpclassifieds, etc.

All 5 websites/domains are up and running well!!!

I can not seem to get the mail working, coming OR going.

I would like to have postfix as the server and squirrelmail as the webmail interface, pop/smtp for the two people who use Outlook. There is only a dozen or so users on 5 domains and a couple of subDomains (I need mailboxes for same user name, but different domains).

Sendmail was sending out web form/page mail but I uninstalled it to install postfix, now NO mail is going out.

Any help would be great!!!

PS.. Can Not Change OS..... it is a Dserver. I have total root access, but not physical access and it would cost $150 to change OS + putting the sites backup.

on the redhat-site you should find something to setup postfix correctly.
in general i think it´s never good to uninstall sendmail, better install your preferred mailserver and link the ´sendmail-files´ to your servers files, in this case postfix.
why don´t you use a more newer distro (e.g. FC3)?

OK ;-)

Could not find anything on the redhat site. rh9 no longer supported and getting around arcives is to confusing for me, without a link to start from (search was no help)...

postfix would not run/bind to port 25 with sendmail running and I did not know how to work around that.

OK I uninstalled the first postfix and installed a new one.

I read all the books & followed the RH "how to" but still I can not get the server to receive mail or send mail, even from a web form or php scripts that were working with sendmail (befor I uninstalled sendmail as per the redhat directions).

I host 5 websites on a dedicated server with a doz or so users. Postfix IS running.
OS=Redhat 9 (no, I can not change OS without a $150 cost), apache 2.0.40, postfix 2.1.5-7.rh9, squirrelmail 1.4.0

I would like to have postfix for pop mail and squirrelmail for web mail access.

following is my /etc/postfix/main.cf file

queue_directory = /var/spool/postfix
command_directory = /usr/sbin
daemon_directory = /usr/libexec/postfix
mail_owner = postfix
myhostname = my.hostname.com (real server HostName (dns name) is Here, not one of the domains)
mydomain = hostname.com (real HostName is Here)
myorigin = $mydomain
inet_interfaces = all
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
unknown_local_recipient_reject_code = 550
mynetworks = my.ip.add.res/28, 127.0.0.0/8
alias_maps = hash:/etc/postfix/aliases
alias_database = hash:/etc/postfix/aliases
home_mailbox = Maildir/
mail_spool_directory = /var/spool/mail
mailbox_command = /usr/bin/procmail
header_checks = regexp:/etc/postfix/header_checks
smtpd_banner = $myhostname ESMTP $mail_name ($mail_version)
local_destination_concurrency_limit = 2
default_destination_concurrency_limit = 10
debug_peer_level = 2
debug_peer_list = 127.0.0.1
debugger_command =
PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
xxgdb $daemon_directory/$process_name $process_id & sleep 5
sendmail_path = /usr/sbin/sendmail.postfix
newaliases_path = /usr/bin/newaliases.postfix
mailq_path = /usr/bin/mailq.postfix
setgid_group = postdrop
html_directory = /usr/share/doc/postfix-2.1.5-documentation/html
manpage_directory = /usr/share/man
sample_directory = /etc/postfix
readme_directory = /usr/share/doc/postfix-2.1.5-documentation/readme
alias_database = hash:/etc/postfix/aliases
alias_maps = hash:/etc/postfix/aliases

Would someone PLEASE tell me what the H*ll I am doing wrong or not doing. this is the last thing I need to have the server complete and working right.

OR if there is a better way to get the mail working the way I need, that I do not know of (some other Daemons, a good name for server programs ) Please tell me how You did it.

hi hivtop,
where do you hang?
any error messages?
does local mail function?

Hi overlord73
>where do you hang?
Mostly on my 58 acers in the sunny High Desert of Southern California... as to the postfix program, It does not >hang, it is up and running.
any error messages?
No error messages in any logs.. and it is not sending mail so there is nothing in the postmaster box
>does local mail function?
Do not have "X" access and I do not know how to send mail locally without it. Postfix will NOT send a, "sendmail type" of request, even from a php or cgi script. so I am at a loss.

I have been playing with this for 3 months and can not get it to work right. I have tried "Vboxes", vertual lists and just about everything I can find to read.

Like Jimmy Buffett sings... "Like the jitterbug, it totally alluds me"...

it's almost to the point of not being fun...

I´m sorry that I can´t help you more....I´m not so familiar with postfix (currently running exim) and my postfix-books are at home....but I´ll do my best ;-)
from console you could use pine or mutt as a mailclient.
or simply via SMTP-commands:

#telnet localhost 25
-> welcome message 220 .... should appear
#HELO host.domain.tld
-> 250 ....
#MAIL FROM: addy@domain.tld
#RCPT TO: addy2@domain.tld
#DATA
´message´
(end with a . in new line)
#QUIT
