We currently have an Exchange 2013 server that hosts all roles for mail in our environment. In front of it we use a product called Modusgate to do our spam/virus filtering.
Lately (at least the last week), the quarantine report that gets generated by modusgate hasn't made it to the users mailbox. If i go into their software and manually generate it , it comes through no issue. I figured it was an issue with them so i overrode the settings and had it send me the report at the same time as the original user. However the next day when i should have gotten it, i couldn't find it and the user didn't get it either. I manually kicked it off and recieved it right away.
So here is the odd part I'm struggling with. The support on the spam filter was able to see in the logs where the message that was scheduled was said to be handed off to our mail server. However if i use the EAC and do delivery reports, any message from postmaster doesn't show up at all so i can't tell where these messages went.
I've checked both the junk mail/quarantine folders in Outlook just in case but no where to be found. I would still think it would show up as delivered in the EAC report.
Any ideas ?
