Currently, that's pretty much impossible to do in spamassassin, and it would be difficult to do without increasing memory usage. Right now, SA just maintains a simple hit list when it scans a message. It doesn't extract the text which matched at all, much less save it where it can be referenced later. Quoting the part of the email that caused the rule to trip is particularly difficult for eval tests, as their code could look at anything or everything. It's also a little tricky for meta tests which wind up triggering as a cascade of other rules trip off. (ie: DRUGS_MANYKINDS). I'd also question who would find such a feature more useful, end users or spammers. Certainly it has some valid uses for end users and non-spammers, but it's considerably more useful to a spammer. For end users it answers the "why did this happen" questions, for spammers it provides useful spam-tuning feedback that makes their spam more effective at evading detection by SA.
