FreeBSD Stable production version.

[Marwan Sultan]

Hello all and Good Morning, Afternoon or evening :)
 
 I finally decided to take off my FreeBSD 7.2 server which is onlin esince 2009.
 
 I will go for a new FreeBSD version and will move out all data.
 
 My Server is mainly is a MAIL server, sendmail.
 and ofcourse few websites, data.etc..
 
 Which version do you recommend? 
 Shall I go for 9 ?
 or 8.3 is still more fit for a production and bsns server ?
 
 Thank you.
