Hi All,

I checked the archives but couldn't find the answer to this question, so 
I apologize if it has be previously addressed.

We recently upgraded from MailScanner 4.56.8 to 4.68.8.  Everything went 
well and we're not experiencing any problems, but I did have a question 
about a comment Julian makes during the install script.  At one point it 

*** You are using a perl configured with threading enabled.
*** You should be aware that using multiple threads is
*** not recommended for production environments.

We are running perl v5.8.8 on CentOS 5.1 and threading is enabled (we 
see "usethreads=define" when we run perl -V).  Is this bad?  Is there a 
way to turn it off?

Thanks again and sorry if this has already been discussed.
