# SpamAssassin sample procmailrc # ============================== # The following line is only used if you use a system-wide /etc/procmailrc. # See procmailrc(5) for infos on what it exactly does, the short version: # * It ensures that the correct user is passed to spamd if spamc is used # * The folders the mail is filed to later on is owned by the user, not # root. DROPPRIVS=yes # Pipe the mail through spamassassin (replace 'spamassassin' with 'spamc' # if you use the spamc/spamd combination) # # The condition line ensures that only messages smaller than 500 kB # (500 * 1024 = 512000 bytes) are processed by SpamAssassin. Most spam # isn't bigger than a few k and working with big messages can bring # SpamAssassin to its knees. # # The lock file ensures that only 1 spamassassin invocation happens # at 1 time, to keep the load down. # :0fw: spamassassin.lock * < 512000 | spamassassin # Mails with a score of 15 or higher are almost certainly spam (with 0.05% # false positives according to rules/STATISTICS.txt).
