Whenever a ticket is created, or a response is made on a ticket, emails are being sent but are getting stuck in the mail queue on our server.
It seems to be due to reverse lookup on the sender email, which is an email for one of our departments, but is returning an incorrect email address.
In the mail log the from header is correct but the sender is something like:
anonymous@12414134.pupip.peer1.com, which is incorrect.
Are extra headers needed for this to work?
