check size of email

[Rajesh M]

hi

is there anyway to check the size of emails or count the number of characters 
in an email using spamassassin ?

basically i wish to mark emails that are less than 2 kb in size with long links 
in them as spam since they mostly spam.

also is there any way to check if a word / excel document contains macros. (i 
do not wish to use clam av.)
