IMAP for D / SIL

Status - usable alpha

Most functions are implemented but parsing responses needs to be done. Uses arsd.email to parse emails including MIME - works currently only if you ask for the whole message - fetchRFC822

Heavily inspired by imapfilter.

Features to add:

• pipeFrom
• pipeTo
• more IMAP extensions

Present, but needs refining:

• currently IMAP literals are only parsed for returns of type responseBody
• only fetchRFC822 works for parsing results (works if you want whole email including attachments)
• mailbox UTF7 conversion code is horrible and needs improving
• more abstraction and better design needed for parsing

Probably many bugs - please file issues. PRs welcomed.
