🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

checkSasl tests can('sasl_authenticator') on a class that is not loaded. Both base patch files carry the same EmailTransport.pm hunk, so the false "Email::Sender 1.300032 or higher is required" message appears in both image families.

  • base-no-s6/2.23.3.patch#L13-L24: load $transportClass with require before the can test.
  • base/2.23.3.patch#L13-L24: apply the identical require guard.

In `@base-no-s6/2.23.3.patch` around lines 13 - 24, Update checkSasl in
base-no-s6/2.23.3.patch lines 13-24 and base/2.23.3.patch lines 13-24 to require
the selected $transportClass before calling can('sasl_authenticator'),
preserving the existing unsupported-transport and Authen::SASL checks in both
identical EmailTransport.pm hunks.
