Teknium 8eb70a6885 fix(email): close SMTP and IMAP connections on failure (#3804) ...

SMTP connections in _send_email() and _send_email_with_attachment() leak
when login() or send_message() raises before quit() is reached. Both now
wrapped in try/finally with a close() fallback if quit() also fails.

IMAP connection in _fetch_new_messages() leaks when UID processing raises,
since logout() sits after the loop. Restructured with try/finally so
logout() runs unconditionally.
