As I mentioned on this list before, I'm switching from Fedora 6 to Centos 5. I'm setting up the mail server and on Fedora I used the milter rpms for greylisting, spamassassin, mimedefant etc. However I don't see that those are included with Centos? Is this true, or do my yum repositories need to be changed to look in an 'extras' location? Or is there some other source for sendmail milter RPMS like on FC6?
