• SEARCH SENTSINCE <date> returns extra outdated emails modern-email/defects#47 -> must be tackled in upper layer
• LIST returns wrong UTF-7 encoded mailbox with & in its name modern-email/defects#46
• Excessive space in EXISTS response (with mailboxes > 500 mails) modern-email/defects#45 -> It seems we shouldn't implement a quirk because the erroneous message is relevant for some other workaround.
• Invalid \* in FLAGS response modern-email/defects#44 -> The defect seems to have been fixed in the meantime
• Winmail Pro Mail Server does not return UIDNEXT after SELECT modern-email/defects#43 -> must be tackled in upper layer
• Invalid NIL in body encoding modern-email/defects#41 -> quirk_body_fld_enc_nil_to_empty
• Descending sequence leads to BAD response modern-email/defects#40 -> Introduce quirk_enforce_ascending_sequence to only emit sorted sequence sets Better handled in an upper layer handle it.
• Gmail happens the send multiple FETCH response for a same seq/uid modern-email/defects#39 -> okay? must be tackled in upper layer
• Proton Mail (Bridge) sends quoted strings with not allowed bytes modern-email/defects#38
• mbsync stores UID in local maildir filenames, and assumes it is unique leading to invalid "duplicate UID" errors when moving files between folders modern-email/defects#37 -> nothing to do in imap-codec
• FETCH RFC822 response lacks RFC822 information in icloud IMAP server modern-email/defects#36 -> upper layer
• Cancellation of AUTHENTICATE is not formally defined modern-email/defects#34
• Unclear base64 usage in command continuation request response modern-email/defects#32
• code and text are ambiguous modern-email/defects#31
• Invalid number (0) in CHANGEDSINCE modern-email/defects#29 -> Won't fix. Since the solution seems to be to ignore the message, we can let the message parser error out so that the fragmentizer skips the message.
• Missing text in HIGHESTMODSEQ response modern-email/defects#28
• Negative number of lines modern-email/defects#27
• Trailing space in SEARCH response modern-email/defects#26 -> feat: Implement quirk_trailing_space_{capability,id,search} + fix panic + clippy #654
• Enforcement of ID before SELECT modern-email/defects#25 -> upper layer.
• Trailing space in ID response modern-email/defects#24 -> feat: Implement quirk_trailing_space_{capability,id,search} + fix panic + clippy #654

• Invalid nz-number in UIDVALIDITY (larger 2^32) modern-email/defects#22 -> won't fix
• Trailing space in CAPABILITY response modern-email/defects#21 -> feat: Implement quirk_trailing_space_{capability,id,search} + fix panic + clippy #654
• Unsupported quoted string/literal in header-fld-name modern-email/defects#19 -> Won't fix. We cannot force a server to accept our valid values, nor is there a way to send an alternative form.
• Standalone CAPABILITY response modern-email/defects#18 -> upper layer
• Empty list in STATUS response modern-email/defects#15 -> done, but no feature. See
• Unsupported ID command variant modern-email/defects#12 -> task for upper layer
