[Dovecot] Dovecot Sieve capabilties - regex

Hi

Does the Dovecot Sieve implementation support the regex capability?

I get the following error when I try to add it:

Jan 3 16:07:30 absinthe deliver(james): sieve parse error: line 1: Unsupported features in require line

The line is:

require "regex";

Thanks

James Turnbull
