Hello,
One of our users can't receive Jira notifications. He is added to project as a customer, and rest of his notification group receiving e-mails normally.
We were checked GMail filters, blacklists, logs, Jira groups, roles, e-mail address correctivity and everything seems to be ok on our side.
Is there possibility that any of e-mail addresses from our domain was added to suppression list and receiving e-mails from Atlassian tools is denied for him?
Thank you in advance for any help.
