Subject: [GSoC PATCH v8 0/2] send-email: improve error capture and status code handling

This patch series improves SMTP authentication error handling.

Auth relied solely on return values without capturing exceptions,
misjudging non-credential errors as authentication failures.

Patch v8 1/2 wraps the auth process in an eval {} block to catch all
exceptions, adds var error for future handling, and var result to return
auth state.

Patch v8 2/2 introduces finer-grained SMTP error handling by extracting
status codes per RFC 5321. For 4yz (transient) errors, return 1 and allow
retries; for 5yz (permanent) errors, return 0. Unrecognized or uncaught
status codes are treated as transient errors (return 1). If no error is
present and no result is defined, return 1 as a transient error; otherwise,
return the authentication result.
