Exchange 2010 on Server 2008 Ent using Exchange built in anti-spam.
I'm having an issue with newsletters not being delivered. I've lowered the spam filter to almost nothing (Resulting in a massive amount of spam) but they're still being blocked.
This is a very big deal to my boss, and I cannot figure it out for the life of me. I've whitelisted the domain - and the domain it's coming from can email us on an individual basis...but the newsletters do not come through.
When the said domain checks their program that sends the newsletters, it shows that the previous attempt bounced and automatically sets them to a disabled status.
This isn't one domain's newsletter - There are multiple.
Has anyone run into anything similar to this before? I can provide any additional information you need. My boss is REALLY on me about this!
