Looking for support from a Message Labs/Symantec employee. Last week I was confused as to why emails from my office to my wife's Gmail were not coming through. Since last week, on July 19th, the messages have come in sporadically. This morning, July 24th, another email came through, 5 days delayed. Looking for an explanation for the delay, and hoping the answer will help others who are asking why their emails aren't being received.
I've attached the internet headers as well as a screenshot indicating the 5 day delay, and also that the mail server in question is on a blacklist, which might explain the issue.
I've removed some identifying information such as the email addresses and subject information of the email. If a Symantec employee wants the intact header please contact me privately.
