Re: [IMail Forum] Constant crashing IMail 10.0 - Unhandled win32 exception occurred in SMTPd32.exe
Using IMail db. I will probably use IMGate down the road, but since I'm not a FreeBSD guru and the situation was dire enough that I didn't have the time to work through setting up IMGate (and I didn't have a machine available to run it), I ended up getting a trial of Alligate and it immediately improved the situation. Have been running problem free since Friday afternoon. Sanford Whiteman wrote: Upon further investigation, the majority of the inbound emails are to invalid addresses at our domain.

Re: [IMail Forum] Constant crashing IMail 10.0 - Unhandled win32 exception occurred in SMTPd32.exe
Upon further investigation, the majority of the inbound emails are to invalid addresses at our domain. We have a backup mail service and in talking to them they say they are getting upwards of 66,000 emaills an hour for our domain during the time our server is out of service. Sounds like a joe-job/backscatter or malicious attack. One of the most appreciated values of IMGate is that it blocks all msgs to unknown recipients before they can overload the IMail server. Unknown recipients is typically 50% of all traffic arriving at the MX. Then greylisting blocks another 40% from hitting the Imail server. Envelope policies and content-scanning handle the rest so that well 10% of MX traffic actually arrives at Imail. From your report, it sounds like Imail 10 still can't handle high-volume attacks. 66000/3600 = about 20 msgs/second.
