yum downgrade?

[Knute Johnson]

There was a recent update to dovecot that caused it to not work.  I 
used yum and deleted the new one and installed the older version.  It 
works fine now.  My question is what will yum automatically update 
dovecot the next time it is run?  Do I need to set something to 
prevent that from happening?  How do I know that there is a fix 
version available if I've disabled updating for dovecot?

Thanks very much,
