Security Notes

The server uses standard Python libraries for IMAP and SMTP (aioimaplib, aiosmtplib). Sensitive credentials are configured via a TOML file or environment variables, rather than being hardcoded in the source. A 'masked()' method is used for displaying account details without exposing passwords. A critical security control is the 'enable_attachment_download' setting, which is set to 'false' by default and must be explicitly enabled, mitigating risks associated with arbitrary file writes. Input validation is present through Pydantic models. No 'eval' statements or obfuscation were found. The primary network interactions are limited to IMAP/SMTP.
