Bug#543391: cyrus-imapd-2.2: Sieve does not decode MIME headers

[Clement Hermann (nodens)]

Package: cyrus-imapd-2.2
Severity: normal

Hi,

Sieve does not decode RFC2231 headers before comparison, so if the
message's header checked is RFC2231 encoded, it will never match.

It means that if you receive a mail with UTF-8 encoded subject, filters
based on the subject content won't be filtered.

This report is mainly for your information : it has already be reported
upstream some time ago as #1721 :
https://bugzilla.andrew.cmu.edu/show_bug.cgi?id=1721

(fix pending, but unlikely to be backported to 2.2.x)

Cheers
