While I like tunables, I don't like this approach. The problem is, the default sucks. I'd prefer to see ALL possible good characters in the source, and the option of setting additional characters you won't allow in the config file, so the default option is best for most people. Cyrus already has too many configuration options for most sites to cope with. Adding more sucks. (also on a technical note: I would put the default in lib/imapoptions rather than testing if the config value existed) Bron.
