I have set up a notification scheme that should sent an email to the reporter of an issue if the issue is changed in any way.
When commenting the issue or editing it in another way, I see the email being added to the mail queue and after a while it disappears. The mail however are never received. I have checked the email address of the reporter and it is correct. It is not listed in the error queue.
I am able to send emails manually from the Send Email page and these are received without problems.
