I believe RFC 3501 is unclear about whether > double-quotes are stripped when an RFC 2822 mailbox is parsed into an IMAP > envelope. I'd like this draft to state double-quotes are stripped (or > un-escaped) if present. I was somehow thinking that all of this came automatically if you parse the address using RFC2822 tokenizer. Like the address could be: From: "Timo" (hello world) "Sirainen" <tss@iki.fi> and the resulting personal name should still be "Timo Sirainen", without double-quotes. I guess it could be mentioned, but to me this seems kind of like band-aid to servers that already parse addresses wrong (if there are any such servers).
