hi.. how do i recover mails?

[Ram]

hi,   my email server uses spamassassin. is there any way i can ‘clean’ all the tags from an assasinated email and recover the original message? many genuine mails have been getting assasinated and it becomes really difficult to read them.. esp when they have html content. and how do i figure out what version of spamassassin my server is equipped with? is there any way of knowing just by looking at an assassinated mail?   thanks, ram
