It's actually not that hard at all Stop, are you joking? Did you ever work in the corporate world? Did you ever have a boss in a large international company?

It might be FUD-like, but it works. Maybe you want to fix the customers mail system for free, do you?

Unfortunately the problem is not going away anyway, with or without cyrus-8bit-2.3.3.diff patch. However, the patch is a good solution for some users of cyrus-imapd and I just don't understand why it's such an issue of discussion now. My congratulations to Ken, who has had a good feeling for the situation when he decided to accept the patch!
