postfix main.cf


i have been trying to use this link
http://www.redhat.com/support/resour...WTO/book1.html
to configure my mail server but this article is not matching the /etc/postfix/main.cf file that i have on my machine there are a few things that are different. all of this myhostname gethostname mydomain getdomainname blablablablabla is really annoying, and really confusing even after reading through some of the postfix site. now i admit im not the smartest person alive thats for sure but if i could find a accurate step by step article for my config.cf file like the link above I'm sure i could get my mail server to work right.

i tried to configure both by hand and with webmin but webmin makes it even more confusing. i cant even imagine what sendmail or qmail is like to configure there suppose to be harder from what i have read.

does someone have a suggestion for a better tutorial.
thanks,
AD

Their are tons of them

You can search for postfix howto

you can check the postfix documentation site. You can read the man pages.

http://www.postfix.org/docs.html

You are trying to do something that is very hard. If you want I can even send you a howto I made up (Have not put up a website yet).

First of all MTA's are confusing and you need to take it slow. It's now like you just slap one together and then go on about your business. Their are so many options it's crazy so you need to take your time and really understand how a MTA works. You need to know the terminoligy and also how it works with the rest of the world (DNS).

I would be glad to help you, I Just need more specific questions.

anyways im going to go back and read more carefully through the postfix site. i was just messing around with something very very cool
http://xhz.freeshell.org/texts/smtp.html i think this is a good place to start too.

That does seem like a good place to start. I have been using postfix for over a year and I am still learning about it. I will send you the howto but be warned it is a little dated it was for RH 7.2 with postfix 1.11.

Good news is a coworker just used it to set up a postfix 2 on a RH 9 system without a problem.

Email sent.

when telneting into my server i keep getting "250 Ok: queued as 13BA674849" after i send the mail. it is sending mail i verified that much.

i can send mail but i cant recieve mail. im not sure why.

in the main.cf file i have tried uncommenting
mynetworks = 127.0.0.0/8, ***.***.***.***/***
and adding my LAN ip range, but this doesnt seem to to do anything for me. i am behind a firewall running NAT could this be the problem?

thanks for any advise,
AD

Well first lets fix the problem in your error log. You need to modify this line in your main.cf

myhostname =

Make it a fully qualified hostname. A fully qualified name contains 2 things a computer name and a domain name.

computer1.domain1.com

So if your domain is schrock321.com a common way of doing it would be

myhostname = mail1.schrock321.com



Ok that should get ride of that one problem and trust me it's very important to get that part right.

Next thing lets see if your mail is just getting qued up.

Type mailq and see if you have a bunch of messages waiting for delivery.

Also please describe your testing to see if you are recieving mail. You may want to try and send to yourself before you send out to another domain. What I mean is try and send to a local user and see what happens. You DNS has to be correct if you want to send out and you also have rely on that the other mail server is not blocking you.
