Hi, I have posted an almost identical patch as part of a suggested fix for "[Bug 1723] Sieve notifications containing UTF-8 are not MIME encoded" though no one seems to be doing anything with it. I added a check to see if the reason contained 8bit and added the headers in only that case. I saw no need to label something with only ASCII as UTF-8.
Fixing notifications with out also fixing vacation as well seemed to be silly; though, I probably should have filed it as a separate bug. There are several other "internationalization" issues with sieve scripts as well as the sieve/lmtpd generated notification and vacation messages. They are documented in Bugzilla: #1710, #1721 - #1725. These probably aren't exhaustive; but, reflect only the problems that have been reported to me. Regards, Mark Keasling <[EMAIL PROTECTED]>
