What/who is doing your spam filtering?
Time to tighten your settings or send a truck load of false negatives to your provider. -

Time to tighten your settings or send a truck load of false negatives to your provider.Or get a new provider. We do our own and while we get some, it really isn't bad at all.

@scottalanmiller definitely something that should remain an option at all times.
How many chances do you give your spam filter SaaS mob? Up to you but draw a line in the sand and stick to it.

We have a Barracuda 300 series. I just applied a firmware update, I thought I was up to date but one just came out a couple weeks ago.
I guess I jumped to our Linux boxes because I just moved two of our servers in house.

Your email is hosted on Linux servers in house? What email server are you using? And is your inbound port 25 limited to ONLY coming through your Barracuda?

No we have Exchange 2016 on a 2012 server. I have 2 servers that are relaying to the exchange server. 90% of the traffic is from in house users so I decided to bring them in house from Linode. I thought I might have had something opened/vulnerable.

All inbound and outbound is set to run through the cuda box.

Set to, but is everything else effectively banned?

Check your windows servers that do not have any strange services, that is what happened to consultant in SW.

yeah, you would want to make sure that the only device getting smtp traffic from outside, is the barracuda.

I used to use a barracuda 300 (for about 6 years) in conjunction with their cloud filtering for our on-prem Exchange 2010 server. I think there were 2 times that they had some sort of issue where they let a crap-ton of spam through, unfiltered.
I have moved to Office 365 and am exclusively using their filtering. I think barracuda was better at filtering. Especially, when it comes to phishing messages that pretend to be from Microsoft's services. You'd think that Microsoft would be able to catch those better than anyone. Not in my experience.
