Header wrapping sucks even more because it's supposed to take the semantic context into account, which means that a generic Header wrapping algorithm cannot work for everything. E.g. Received: headers are supposed to wrap after the semicolon. The current email package does a pretty poor job of emulating this requirement, though it often gets it right enough. David has plans for addressing this problem. -Barry
