I investigated a bit on this issue.
Sieve specification says:
----
The ":matches" version specifies a wildcard match using the characters
"*" and "?". "*" matches zero or more characters, and "?" matches a
single character. "?" and "*" may be escaped as "\\?" and "\\*" in
strings to match against themselves.
----
This means only * and ? are special chars.
Instead jSieve uses a Glob expression compiler for the matches operator:
http://james.apache.org/jsieve/xref/org/apache/jsieve/comparators/ComparatorUtils.html#104
http://jakarta.apache.org/oro/api/org/apache/oro/text/GlobCompiler.html
The problem is that a Glob expression supports much more than * and ?.
So what is the solution to this?
One solution is to write a custom oro.text.regex.PatternCompiler and use
it. Another solution is to escape some of the chars in order to make the
GlobCompiler work with * and ? only.
Otherwise we could rewrite the input string to a Perl5regexp or a java
regex before compiling.
IMHO it is interesting to note that jSieve depends on ORO just for this
class, so maybe the best thing would be to write our own matcher or to
use builtin java regex.
WDYT?
As a side note: why the ComparatorUtils uses the weird
get/getBasic/update/set/compute pattern for the GlobCompiler and for the
Perl5Matcher given that they are private and used only by static methods
(so I see not really a single advantage over a simple lazy
instantiation, because it could not anyway be overridden) ???

Open square bracket as first char in matching pattern does not work

Key: JSIEVE-19
URL: https://issues.apache.org/jira/browse/JSIEVE-19
Project: jSieve
Issue Type: Bug
Affects Versions: 0.2
Reporter: Stefano Bagnara
Fix For: 0.2
this rule
if header :matches \"X-Caffeine\" \"[test]*\" {throwTestException;}
does not match for
X-Caffeine: [test] something
Removing the open square or moving it as the second char instead works.
