No, they're not. The 'condtion' clause in the ACL above doesn't control
whether the message gets sent to SA or not - it is evaluated after the
message was scanned and controls the 'warn' clause - hence its usual use for
checking the returned $spam_score before messing with headers or whatever.
If you want to place a condition on whether the message gets scanned, you
need to do what Bruce suggests and put an expansion (maybe a $if{ )in the
'spam=' clause that evaluates to false or zero to prevent scanning, or to
'nobody:true' to cause scanning to take place.
Something like this (untested):
spam = ${if <{$message_size}{50k}{'nobody:true'}{0}}
