Thumbs up Centos 4.2, removing sendmail and installing postfix from yum

When you order your new server. Allot of data centers run Centos server on their servers. Centos server comes complete with a compiled list of programs that you may or may not use. And If you plan on running Webmin on your server. You are going to want to remove sendmail and install postfix. The process can be done by doing the following.


The first thing we are going to do is log into SSH and remove sendmail with the following command.

#rpm -e sendmail

This will remove the sendmail instillation

Next we are going to install postfix using yum. Type the following command.

#yum install postfix

Type y to confirm

Thats all there is to it. You have now removed sendmail and installed postfix.

Default Centos 4.2, removing sendmail and installing postfix from yum

Change mycompany.hosting to your real domain name , and use that everywhere
instead of mycompany.hosting
for example if your domain name is bigcompany.com you will use bigcompany.com
everywhere in this guide instead of mycompany.hosting!!!!


!!! Read this !!!
If you used bigcompany.com for fqdn (mail.bigcompany.com) , you cannot use
the same domain name for virtual domains, since postfix will not work, this is
a critical error i made in this guide, sorry.

Default Dealing with rpm dependencies

If you've got anything on your box that claims to have dependencies on sendmail and you get any error messages when trying to do the rpm -e sendmail, you might add --nodeps to the rpm command. This should leave other dependent packages in place.
