| # 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. | 
 | # |

 |  | 
 | # Mails with a score of 15 or higher are almost certainly spam (with 0.05% | 
 | # false positives according to rules/STATISTICS.txt). Let's put them in a | 
 | # different mbox. (This one is optional.) | 
 | :0: | 
 | * ^X-Spam-Level: \*\*\*\*\*\*\*\*\*\*\*\*\*\*\* | 
 | almost-certainly-spam | 
 |  | 
 | # All mail tagged as spam (eg. with a score higher than the set threshold) | 
 | # is moved to "probably-spam". | 
 | :0: | 
 | * ^X-Spam-Status: Yes | 
 | probably-spam | 
 |  | 
 | # Work around procmail bug: any output on stderr will cause the "F" in "From" | 
 | # to be dropped.  This will re-add it. | 
 | # NOTE: This is probably NOT needed in recent versions of procmail |
