caratking,

We're adding that option to the new SpamFilter 3.5 release. There's a beta version available in the registered user area, and it will be another month or so before it is released officially.

I did a search today for EHLO to see about this issue today, and came to this thread.

Has this feature been implemented to the EHLO states the FQDN? My server still seems to report the windows machine name when connecting.

Alex,

If you have 40-80 concurrent connections at anytime, that will generate a lot of events in the activity log. If SpamFilter's *GUI* is slow, it's possible that your video card is not able to handle the amount of scrolling that occurs in the "Activity Log" and/or "Connections" tabs in SpamFilter. Try to de-activating both displays (with the "Enable Activity Log" checkbox on the ActivityLog tab, and the "Disable Conns Grid" checkbox on the Settings-Configuration tab).

If you receive in the order of a few millions emails/day, we'd recommend disabling the Bayesian filter as well, as it requires a lot of resources and is not that effective/accurate in high traffic installations. Bayesian filters were "ok" to use a few years ago, but nowdays spammers can easily word emails to go around them.

Personally in this situation I would be denying anyaccess of anytype at the firewall level on some subnets.

Great. Yeah, my destination server is set up to verify RDNS on the EHLO message, and so I got a bunch of warnings whenever SpamFilter sent a message to it.

Overall I really like your product! However, I have some severe performance issues. I'm running it on a dedicated Windows 2000 server at this time, whenever SpamFilter is active, the system acts very very slow in the Gui.

Under the "Settings - Configuration" tab, the entry for the "FQDN" is the Fully Qualified Domain Name that will be used in the welcome banner SpamFilter will send to the connecting servers.

The domain in the EHLO command that SpamFilter uses when forwarding emails to your destination SMTP server is fixed to the primary machine name. Strange that in the last 4 years nobody noticed this! You have a very valid observation, and we will be adjusting this to match the FQDN in the welcome banner in the next release.

How do I set the argument to EHLO to the server name I want to use. At this point EHLO simply identifies itself as the primary machine name, but not as the DNS entry for the IP addressed used.

Thanks -alex
