We've been having sporadic problems with mail coming from our OnDemand instance; mail sent to multiple folks in tests are taking upwards of 90 minutes to get out of JIRA, regardless of where the mail is being sent, including large mail providers such as gmail or hotmail.
The problem appears to be the mail queue outbound from Atlassian - I can send an email from there and get a response at numerous places less than a minute later, but other tests to the same folks show longer lead times - and everybody receives it at the same long lead time, so it's not the recipient's issue.
Is there any way to determine where something is in the Atlassian mail queue (not my JIRA instance to the Atlassian mail server queue - that part is very quick)? Or get an idea of the delay at the Atlassian mail queue? For a cloud-based SaaS instance, this is unusual - I would expect resources adjust to the needs of the system and not have such delays.
