   Verified the reconnect fix in #74416 against 
`apache-airflow-providers-smtp==3.1.1rc1` installed from PyPI on Python 3.11.16 
in an isolated Breeze container. The imported SMTP hook was confirmed to come 
from the installed RC package, not the source checkout.
   
   - Reusing the same synchronous and asynchronous hook across two 
context-manager entries successfully sent both emails.
   - Calling the same notifier twice successfully reused its cached hook with a 
fresh SMTP client.
   - Client state was cleared even when synchronous `close()` or asynchronous 
`quit()` raised; the cleanup errors still propagated.
   - Local Mailpit captured all six expected messages. SMTP provider 3.1.0 
reproduced the second-send failures as a negative control.
   
   The RC tag contains the merged fix and its changelog entry. This is focused 
verification of the reconnect fix, not a full release-artifact audit or 
supported-core-version matrix; the core/common dependencies used Breeze's 
development baseline.
