Answer : help with postfix and mysql (unsupported type)

This is a problem with postfix. The thing is that many users don't choose to use postfix with mysql, so it comes disabled by default.
You need to get the latest source rpm and run it with -Uvh. Then go to the directory /usr/src/redhat/SPECS/and you will find the postfix file with .spec. Edit this file and at the top where it says mysql, change the value 0 to 1.
then rpm build -bb that file. Then go to /usr/src/redhat/RPMS/and find the file that was created. Run this file using -Uvh and that's it. To check that postfix has mysql compatability run postconf -m and see if mysql is in the list.
that's it. Hope this helps.
