Email Alerts are not received...

In one of application, Email alerts are sent using SQL sp_send_dbmail stored procedure. Email alerts were working properly, but suddenly noticed email alerts are not received.

To troubleshoot the issue, first I checked the msdb.dbo.sysmail_event_log table using the below query.

SELECT log_id, event_type, log_date, description, process_id, mailitem_id, account_id, last_mod_date, last_mod_user
FROM
msdb.dbo.sysmail_event_log 
ORDER BY
log_date DESC

If there is any error, you should see records with the event_type value as error.
In my case there are records with event_type value as error, and the description value for those records is same as below

The mail could not be sent to the recipients because of the mail server failure. (Sending Mail using Account 3 (2018-02-01T10:41:27). Exception Message: Cannot send mails to mail server. (The SMTP server requires a secure connection or the client was not authenticated. The server response was: Authentication required).  )

Problems when trying to get changed records from...

The SSIS Package was configured to get only the net changes by applying the CDC processing mode as Net in the CDC Source.
But when the SSIS package was executed, got the below error message.
"Problems when trying to get changed records from dbo_testcdc. Reason - Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding..".

The issue was fixed by using the below steps.


Right click on the CDC Source and select Properties.In the properties window find the Command Timeout and change it to 0. Default value of this property is 30.Save the package and execute it. It should run without any issue.
