Email cannot be send to the User (Error: 530 5.7.1 Authentication required )

Hi Team,

I have used Yahoo IMAP Account for the  EMAIL integration  while configuration the test was successful , but as user raise the  ticket email does not come.

I checked by Email settings Incoming is green and Outgoing is also green when i send email for approval of ticket it though following error:

Ticket 4 was saved successfully.

Could not send e-mail to User1 <user1@yahoo.com>

due to the following error:

530 5.7.1 Authentication required

Could not send e-mail to User2<user2@yahoo.com>

due to the following error:

530 5.7.1 Authentication required

I am new to this tool please suggest

Now it is working by sending successful sending mail . But unabale to see any mail in INBOX.

And In email Configuration Email History shows Email send.
