imap_add_accountAdd a new IMAP account configurationimap_update_accountUpdate an existing IMAP account. Useful for fixing SMTP settings without removing and re-adding the account.imap_list_accountsList all configured IMAP accountsimap_remove_accountRemove an IMAP account configurationimap_connectConnect to an IMAP accountimap_disconnectDisconnect from an IMAP accountimap_test_accountTest an existing account connection without re-entering credentials. Validates IMAP connectivity and returns folder count and message count.imap_search_emailsNote: on some servers a 'flagged' or starred message carries a custom keyword (e.g. an Open-Xchange color label or Apple's $MailFlagBit*) instead of, or in addition to, the \Flagged system flag. After any flagged search, inspect each result's customKeywords field before concluding a message is or isn't flagged — do not rely on the flagged filter alone. Search for emails matching criteria (sender, recipient, subject, body text, date range, read/flagged status). Use this to FIND messages when you know something about them but not their UID — e.g. "emails from amazon last week", "unread invoices". By default searches a single folder (INBOX). Set searchAllFolders=true to scan every mailbox at once — this catches messages filed away by rules (e.g. a receipt routed to a custom folder); Trash/Spam/Drafts are skipped unless you opt in. By default returns lightweight headers (uid, from, subject, date, and folder when searching across folders); set `includeBody=true` to also return the parsed body in one round-trip instead of paying the N+1 cost of calling imap_get_email per match. For the newest messages without criteria, prefer imap_get_latest_emails.imap_get_emailRead the FULL content of a single email by its UID (body, sender/recipients, date, attachment list, optional raw headers and text-attachment previews). By default the body is returned as clean Markdown in markdownContent and raw HTML is omitted so it never crosses the boundary; set bodyFormat to "html" for the legacy raw htmlContent, or "text" for plain text only. Use after imap_search_emails or imap_get_latest_emails gives you a uid. Body text is truncated to maxContentLength to protect the context window — raise it for long messages. To fetch attachment bytes, use imap_download_attachment.imap_upload_fileUpload a file to the server for use as an email attachment. Returns a path that can be used with imap_send_email attachments. This allows sending large attachments without hitting context window limits. Max size: 26214400 bytes (configurable via IMAP_MAX_UPLOAD_SIZE). Uploads are auto-deleted after 86400000 ms (configurable via IMAP_UPLOAD_TTL_MS).imap_download_attachmentDownload a single attachment from an email (folder + uid + attachment filename/contentId, as listed by imap_get_email). Images are returned inline for viewing; PDFs are saved and their text is extracted inline (extractText); other files are saved to the shared downloads directory (or savePath). Use when the user wants the actual file contents, not just the message body.imap_mark_as_readMark one or many emails as read. Accepts a single UID or an array — pass an array to flag N messages in one IMAP STORE round-trip (useful when triaging).- +28 more on the listing page
