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
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).  )

Unable to process the cube after restoring to a different server...

There was an error while trying to process SSAS Cube, after restoring the cube to a different server in the same domain. The initial error shown related to credentials.
The following system error occurred:  Logon failure: unknown user name or bad password. 

Actually it is due to that the SQL Server user password is not saved. I provided the password and tried to process the cube again. But I got a different error message as below.

The following system error occurred:  The security database on the server does not have a computer account for this workstation trust relationship. 

There are different approaches mentioned in various sites to fix this issue. But I was able to easily fix this by changing the ImpersonateAccount to a domain user who have access to the Analysis Service. The user initially used was not a domain user.
Therefore if the same error is thrown, try to apply this fix and process the cube.
