please suggest me please for a mail server in FC5.
if sendmail is better? or postfix or Exim?
please answer in a Details and please send me a setep by step Configuration for the best mail service.

regards

Most people I talk to recommend Postfix over sendmail for increased functionality and ease-of-use (including an RHCA guy I spoke to on a course) - see http://www.postfix.org/start.html for everything you need to know, I'm sure you'll find your step-by-step guide on there or google...

You should really think about using a supported distro for a server, since FC5 is off lifecycle.

Why don't you try CentOS 5 if you like the Fedora setup. CentOS 5 is basically RHEL5, which in turn is largely based on FC6.

I'd seconf the postfix recommendation above, but you will need to do some reading.

Personally, postfix..

I had very good experience deploying postfix on Centos.. But I used the vanilla built-in postfix v2.3 that came with Centos. Runs perfect, never had any problems after running it close to 2 years now.

If you're feeling adventurous, try the Postfix RPM Archive at http://ftp.wl0.org where there are RPMs specifically built for RHEL5 (of course centos compatible) at http://ftp.wl0.org/official/2.5/RPMS-rhel5-i386/

These are the latest postfix versions for RHEL5/Centos5.

Hope it helps..

postfix is far better thatn sendmail

Hi ,

I would recommended you to use Qmail as mail server. once its configured we will find the difference from other Linux Mta.

qmail parallelizes mail delivery, performing up to 20 deliveries simultaneously, by default.

Some of the advantages of qmail over vendor-provided MTA's include:

Once qmail accepts a message, it guarantees that it won't be lost. qmail also supports a new mailbox format that works reliably even over NFS without locking.

Support Maildir format.

Link to configure Qmail:- http://qmailrocks.org/

Best of Luck buddy..............

Sorry but I disagree with you "Koushik Biswas"

I have configured qmailrocks 3 times in a row and found same problem
"RELAY"
My server is used by someone to send spam to someone else.
I can't stop this RELAY
Also the online documentation on qmailrocks.org is not sufficient on topic of RELAY.

Any comments???

I found several references to turning off/restricting relay access on their site, and on Google. Seems fairly easy to do...

I have qmail and tested it for relaying using http://www.abuse.net/relay.html

It passed all tests.

Hi,

stop qmail using "qmailctl stop" command, then add aliases into /etc/tcp.smtp file
for example :
echo '172.16,allow,RELAYCLIENT=""' >> /etc/tcp.smtp
this will allow relay from anybody on 172.16.*

then rebuild qmail config.database using "qmailctl cdb" command, then start qmail "qmailctl start"

What is better is largely a matter of first function and second opinion.

If your mail server is sending 2m mail a day your considerations are going to be significantly different than if you're sending a half dozen mail a day. Someone dealing with virtual domains for 100 sites and someone dealing with 1 domain are going to have different requirements too.

I've personally used exim, postfix, qmail, and sendmail (and dozens of less known MTAs) extensively for many years and I can guarantee you that they all have their high points and low points, but they are all functional mail transport agents able to do just about anything you are willing to spend the time to configure.

To make a good suggestion we need information about the planned usage of the mta. If your usage is fairly normal any of them are going to be more than able to do the job.

I would suggest reading the tutorials on http://www.howtoforge.com/ as a starting point or read information about the goals of each of the mail clients on their home page or Wikipedia articles.
