Our take

Mailoo provides an MCP interface for IMAP and SMTP, including multi-account support and per-folder profiles. It is useful for agents that need direct email read/send workflows, though the lack of visible package metadata or usage signals means deployers should review its security model carefully before connecting real mailboxes.
