New method of spoofing?

My VP of Sales has been getting a bunch of emails that look pretty convincingly like they're coming from his account. It's a poorly-spelled bitcoin extortion attempt. Info from quarantine on EFA, which seems like a message sent to himself: Message Headers: Received: from relay1.live.com (unknown [10...

Thanks

There were only a few employees being spoofed (one of which was the CEO) so the rule says if the email comes from outside the organization with the FROM header having certain values (names of employees) then delete ...

Remote users unable to access MailScanner web page

When logged on to the AD domain on location or by VPN, users can click the link at the bottom of quarantine notifications to release them. But remote users cannot. I've opened up port 80 on the firewall, and have rules to NAT ports 25 and 80 to the internal address. I've checked the firewall on the ...

my default gateway is causing a 4.7.1 rejection on all inbound

I'm trying to set up version 3.0.2.6, using my old system as a template (EFA, but years old and not updated). I changed the NAT on my firewall to direct incoming mail to the new EFA device and I'm getting the following error on ALL incoming emails: NOQUEUE: reject: RCPT from unknown[10.5.4.244]: 450...
