@Mimecast Your tech support in the last 12 months has gone to sh*t. I had a critical issue last week and it took 4 days just to get a response, much less a fix. Most support incidents now take 2-3 days to get an answer, whereas it used to be 4-6 hours.

@nekodeev @gmail Yeah, Iâve been deploying @SwiftOnSecurityâs Exchange rules for years with great success. Mimecast is getting better at catching this garbage lately too.
Problem is Gmail at the core. They have the power to stop this, but clearly DGAF.

Going down to check with Packet Control to see if the ICMP layers are heated the way they should be. I need to bring a crowbar, because at the Mimecast levels there are rats.
I know bull**** in my job. Do you know bull**** in yours? Digital evidence is transient at best.

Holy **** the @gmail based payroll fraud #phishing campaigns are firing full tilt.

Instead of launching a new version, how about you fix your fraud problem first?

@notroygreen 1) Domain setup test. (fix the easy stuff)
2) Seed test. (find out if you're getting into mail systems used by businesses, GSuite, Office365, Mimecast, Proofpoint, etc..)
3) DMARC Monitoring (compliance/compliants)
regularly check all 3. need to track it.

@cfenollosa Why not use mimecast or proofpoint to not publicly give out your IP via DNS records, allow spoiling if your server or ISP is down, and give you some spam filtering tools yourself? As long as you set it up for inbound and outbound, your deliverability problems should go away.
