Anyone else having issues with database mail after installing CU23?  I installed on two separate servers that use two different SMTP servers, and neither will send emails now.  Records in msdb.dbo.sysmail_mailitems indicate a sent_status of 0 (unsent).  No new records in msdb.dbo.sysmail_faileditems.  is_broker_enabled = 1 for msdb.

Tested on a SQL 2019 instance that uses one of the same SMTP servers, and email was successfully sent.

Incidentally, seeing the same issue for 2025 CU1 that was also released yesterday.
