James,
I got another issue trying to migrate from current cyrus installation
(cyrus-2.4.17) to new one with imap4flags extension: bytecode is not
compatible with old compiled - "sieve runtime error: Invalid sieve
bytecode"
This happens when "fileinto" was used in compiled with cyrus-2.4.17
sieve script. Any other sieve target looks to work just fine.
Best,
Deniss
