A couple of clients are not able to reply by email to the emails they get when I update their tickets.
e.g., I reply on a ticket back to them.
They get an email from jira@<name>.atlassian.net.
They reply to that email.
Nothing else happens.
The comment doesn't get added to the ticket.
This is working for other people?
And it's working for me.
Anyone know what could be wrong?
