.SH "NAME"
Mail::SpamAssassin::Plugin::ReplaceTags \- tags for SpamAssassin rules
.PP
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.
.PP
Warning: This plugin relies on data structures specific to this version of
SpamAssasin; it is not guaranteed to work with other versions of SpamAssassin.

.IP "replace_tag tagname expression" 4
.IX Item "replace_tag tagname expression"
Assign a valid regular expression to tagname.
.Sp
Note: It is not recommended to put quantifiers inside the tag, it's better to
put them inside the rule itself for greater flexibility.
.IP "replace_pre tagname expression" 4
.IX Item "replace_pre tagname expression"
Assign a valid regular expression to tagname.  The expression will be
placed before each tag that is replaced.
.IP "replace_inter tagname expression" 4
.IX Item "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.
.IP "replace_post tagname expression" 4
.IX Item "replace_post tagname expression"
Assign a valid regular expression to tagname.  The expression will be
placed after each tag that is replaced.
.IP "replace_rules list_of_tests" 4
.IX Item "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.
.IP "replace_start string" 4
.IX Item "replace_start string"
.PD 0
.IP "replace_end string" 4
.IX Item "replace_end string"
.PD
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.
