Re: Help withsetting up mail servers

You should be aware the errata for RH9 on fedoralegacy.org are backports
of
stuff from Fedora, and are a bit slow and spotty. You really should be
using
a more modern distribution (FC4 is current, FC5 is in beta, and should be
out in March). RH9 came with

postfix-1.1.11-11 errataed to 1.1.12-1
sendmail-8.12.8-4 errataed to 8.12.8-9.90

I am forced to use RH9 on our servers as they are older PIII machines with
video cards not supported by X.org. Maybe if I could either update the X.org
Cirrus Logic video driver or use XFree86 with FC1 ? But I gave up on doing
either of those things.

RH9 seems fine on these old servers.

Mail servers _are_ MTA's (Mail Transport Agents). You might want to look
at

Sendmail-Address-Rewrite

okay

Sendmail is the dominant player, and comes with a lot of documentation.
See
also the news group 'comp.mail.sendmail'. Postfix is considered by many
to
be an easier one to set up. Your choice.

Yes I have decided on Postfix.

If you are intending on sending mail from your system _directly_ to users
on the Internet, be aware that many ISPs block port 25 - mainly to reduce
zombie spam.

Okay, how do you get round that ??? Whats the proper proceedure for sending
mail to users ?

Many ISPs also use blocklists (a.k.a. blacklists) to block
mail from spam sources, which may include significant numbers of ISPs,
and IP addresses that are not clearly established mail servers.

Okay I have a BL based Anti Spam utility on my Windows machine called
SpamPal, its very effective !
I hope to use SpamAssassin on my server.

Do a DNS
lookup of your IP address, and hostname and see if they match, and do not
appear "generic" or "dynamic".

The DNS should be fine, its static, directly mapped to my static IP.

For further details, read the FAQ for the
moderated newsgroup 'news.admin.net-abuse.blocklisting' and at least scan
that group.

http://www.blocklisting.com/faq.html thats very useful infomation :)

Thanks Moe.
