mailscanner 4.66.4-3 reccomendation

[James N. Smith]

Need some advice from the list.  I am doing a new install based on CentOS 
5.1.  I have run into the MailTools v.2 problem trying to run MailScanner 
4.65.3-1.

Is it recommended to use the MailScanner 4.66.4-3 Beta with MailTools 2.02 
or try to revert to an older version of MailTools and use the stable 
MailScanner?

More specifically, is 4.66.4-3 a reliable beta (more akin to a Release 
Candidate) or is it more "buyer beware"?

Thanks in advance!

James
