NAME

       Mail::SpamAssassin::Plugin::ReplaceTags - tags for SpamAssassin rules

       The plugin allows rules to contain regular expression tags to be used in regular expression rules.  The
       tags make it much easier to maintain complicated rules.

       Warning: This plugin relies on data structures specific to this version of SpamAssasin; it is not
       guaranteed to work with other versions of SpamAssassin.

RULE DEFINITIONS AND PRIVILEGED SETTINGS

       replace_tag tagname expression
           Assign a valid regular expression to tagname.

           Note: It is not recommended to put quantifiers inside the tag, it's better to put them inside the
           rule itself for greater flexibility.

       replace_pre tagname expression
           Assign a valid regular expression to tagname.  The expression will be placed before each tag that is
           replaced.

       replace_inter tagname expression
           Assign a valid regular expression to tagname.  The expression will be placed between each two
           immediately adjacent tags that are replaced.

       replace_post tagname expression
           Assign a valid regular expression to tagname.  The expression will be placed after each tag that is
           replaced.

       replace_rules list_of_tests
           Specify a list of symbolic test names (separated by whitespace) of tests which should be modified
           using replacement tags.  Only simple regular expression body, header, uri, full, rawbody tests are
           supported.

       replace_start string
       replace_end string
           String(s) which indicate the start and end of a tag inside a rule.  Only tags enclosed by the start
           and end strings are found and replaced.
