+=head2 email
+
+This plugin collects data indirectly by providing a UNIX socket that external
+programs can connect to. A simple line based protocol is used to communicate
+with the plugin:
+
+E-Mail type (e.g. "ham", "spam", "virus", ...) and size (bytes):
+
+  e:<type>:<size>
+
+Spam score:
+
+  s:<value>
+
+Successful spam checks (e.g. "BAYES_99", "SUBJECT_DRUG_GAP_C", ...):
+
+  c:<type1>[,<type2>,...]
+
+Each line is limited to 256 characters (including the newline character). 
+Longer lines will be ignored.
