Postfix with MySQL support?

[Lonnie Cumberland]

Hello All,

I have been working to get Postfix installed and set up but seem to have 
run into some problems.

I used "Yum", which I think is a GREAT tool, to install Postfix but is 
does not seem to have MySQL support installed and I am wondering where I 
can get the RPM with that compiled in or if some one might give me some 
guidance on how to get it done?

Actually I was following an article which asked me to modify:

/etc/postfix/mysql-aliases.cf
/etc/postfix/mysql-relocated.cf
/etc/postfix/mysql-transport.cf
/etc/postfix/mysql-virtual-gid.cf
/etc/postfix/mysql-virtual-maps.cf
/etc/postfix/mysql-virtual-uid.cf
/etc/postfix/mysql-virtual.cf

but these files do not exist with the Postfix installed from Yum.

How can I fix this?

Thanks in advance for your help,
Lonnie
