Hello Rob,
I see nothing wrong to encode ordinary ASCII headers with ?koir-8?
style. If you want to check against headers containing Cyrillic letters,
then
if header :contains "subject" "е" { ... }
shall do the work, where "e" is Unicode 0435.
Със здраве,
Дилян

We're a large cyrus installation, and I recently got an email from a

headers when doing sieve header matches.
I looked through the cyrus code, and I think the fix is actually pretty
easy, but it occured to me that in fixing this, we completely loose the
ability to match against the non-decoded headers. That's actually
annoying because I know a number of people do that to try and block
emails with particular character sets in the subject line. For instance
I know people have script tests like this:
if header :contains "subject" "?koir-8?" { ... }
To catch and drop all emails with Russian subjects.
By fixing this bug, it would break those existing scripts, and from what
I can see in the RFC, there's no way to actually force a match against
the non-decoded header (eg no :raw option or something like that).
Am I missing something? Is there a way to make a header match against a
non-decoded header?
