Email IMAP/SMTP

Connect to mainstream email providers and perform reliable send/receive workflows through IMAP and SMTP with password or OAuth2 authentication. Use when a user asks to add mailbox accounts, test login, list unread/recent emails, read message bodies, search emails by sender/subject/date, refresh OAuth2 tokens, or send emails (with optional HTML and attachments).
