[GSoC PATCH v4 0/2] smtp_auth_maybe: unified error capture and status code processing optimization

This v4 patch series includes two improvements:

1. Unified error capture:
Consolidate exception handling within a single eval block by introducing
local variables to store results and error states, thereby streamlining
code structure and enabling future extensibility.

2. Status code processing optimization:
After catching the authentication exception, parse the three-digit status
code in the error message, For temporary errors (4yz), only print warnings
and return success, while for permanent errors (5xx), return failure,
Unrecognized status codes are treated as permanent errors by default.
