160 #### COUNT
161
162 COUNT is similar to SCAN, in that it uses a defined SEARCH and breaks it up according to a PATTERN. Then it
163 counts the number of results.
164
165 For example, to block every message with more than one URL:
166
167 # Define a search location called 'body' which fetches the text of the 'body' element
168 %SEARCH body: body#
169 # Define a pattern called 'url' which matches HTTP links
170 %PATTERN url: https?://%S+
171
172 COUNT: url in body > 1
173 BOUNCE=policy-violation (Up to one HTTP URL is allowed in messages)
