Postfix Setup Questions?


I recently installed Red Hat 9.0 and find that both Sendmail and Postfix are installed on the server. If I want to use Postfix do I need to remove Sendmail? Can I install the new version of Postfix over the existing one? Also, Is there a way to make Postfix the default MTA?

Thanks,
Frank

Frank,

I'm just about to configure Postfix after having tested at work on Redhat 8, we found this link that was helpful (although for Mandrake but still useful):-

http://www.jennings.homelinux.net/ma...er_config.html

As to your specific questions, we didn't actually remove sendmail, just stopped it being loaded as a service at start-up.

As for upgrading, on all Redhat versions we use a combination of Apt-get & Synaptic for managing patches/upgrading, very reliable and makes package upgrading a breeze. AFAIK once you disable sendmail and enable postfix, postfix is your default.

To configure postfix we used the (latest) webmin module, the only options we changed from the defaults are (for fixed ip, inbound port 25 forwarded to server & using a DNS management service) :-

*General Options*

What domain to use in outbound mail - Use Domainname (i.e. actual mail domain equals domain of our server)

What Domains to receive mail for - Whole domain

Send outgoing mail via host - Deliver directly

Network interfaces for receiving mail - All

*Mail Aliases*

Root - ouradminaccount@ourdomain.org

*Local Delivery*

Destination address for unknown recipients - postmaster@ourdomain.org


We got so far and it all appeared to be working ok, however we could not find for certain that we could deny it being used as a relay so we shut it down until after the holidays. Also we intend to do some serious research to look at the config more closely, there is a wide gap between working and working correctly :-)

HTH

regards

Chazza

Thanks a lot for your excellent reply. I will check out the link and use your suggestions when I configure my server. BTW how do I disable Sendmail? I assume that just stopping the service will not disable it forever.

Thanks again,
Frank

I found this postfix howto very helpful when I set up postfix:

http://postfix.state-of-mind.de/patr...tter/smtpauth/

It discusses how to disable and remove sendmail.
