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