Can anybody help me? I've installed mutt+spamassassin and added this lines to my .muttrc file:

macro index S "|/usr/bin/spamassassin -r"
macro index H "|/usr/bin/sa-learn --ham  --no-sync"
macro index R "!/usr/bin/sa-learn --sync"
the problem is I don't know how to select multiple mails to be examined by spamassassin.

I've tried to select (pressing 't') the messages and then writting ';S' but it doesn't work...
