Hi all,
I had lots of spams on some of my clients' domains on my ded server on total control, and just a month ago I bought Spirus on one of them to give it a try. but the results do not seem to be awesome... I still got a lot of spam emails on it.
I took a look to the cp but it doesn't seem to be very helpful. any suggestions how can I make it more efficient?
thanks and regards in advance for your kind advices,
Emad

I see a couple of things:
First and most importantly, none of the mail from the domain you signed Spirus up for is passing through Spirus. Before it will pass though Spirus, you have to set the MX record to inbound.filter.theplanet.com. Take a look at 1504205PLNT for more detail.
Second, tell your customer to set filters in their mail client to filter mail with the header "X-Spam-Flag: YES" to a spam folder. If they're using a mail client that has an option in the filtering setup to mark this mail as Spam use that (this will train the local mail client on what's spam and what's not).
Third, spam filtering works best in layers. This is because each domain gets a different mix of mail, both legitimate and illegitimate. Spirus is pretty good at getting almost all of the spam it sees, but if a domain normally gets an out of the ordinary payload, it may not be as efficient is trapping this mail or other spam that's passing through your domain. A filtering agent on the user's mail client, or on the server we relay the mail through as a second pass is very likely to trap it's own set of spam.
Spam filtering is especially problematic. Image spam doubly so. The two things above (plus sending your mail through Spirus) should out quite a bit. If you still have issues, open a ticket so we can take a look at what's still getting through.
