Emails are not sent if one of the email id is no more valid

[SuhailM]

Hi,

I have a service which use JIRA mailing APi to send emails.There are some users who do exist anymore .becuase of them the whole email is not sent .I want to send email to all the users who exist and i really dont care if the email is not sent to the users who do not exist anymore.How can i Change this setting in JIRA-

I get the following error-

Sender address rejected: User unknown in local recipient table ; nested exception is: com.sun.mail.smtp.SMTPAddressFailedException: 550 5.1.0 <admintest@<company>.com>: Sender address rejected: User unknown in local recipient table

As i said I want to send email to the reciepient list of which contain some valid users and some who do not exist.

Them ails often get errored out in and fill in ErrorMailQueue

I think this is the same error is reported in this bug - https://jira.atlassian.com/browse/JRA-26273

I am not sure if there is any setting for this, seems to be a plain bug.
