Thanks. We'll let you know when a new response is added.

first thing first. do you have an anti-spam. If yes juste make sure your domain is not wite listed. if not bye or rent one and this will fixe your probleme.

Spamers are smart and will seek all sort of way to distribute their junk.

good lock

****************
“Spoofing” or imitating your email address is a very common spamming technique. Third-party spam blocking software or a third-party vendor who will do this for you are your best options. It depends on how much money you want to spend or how much time you want to devote someone’s job to this. Controlling it yourself will take almost a full-time employee, outsourcing to a third-party vendor relieves you of the responsibility and some guarantee a 95% reduction of SPAM. It really depends on what your company decides is the best option.

Try implementing a mail proxy or spam filter in front of your exchange server. We use a Sophos ES4000 and it works great. It is blocking 40,000 spam and viruses every day. It is definitely something to consider.

    If more administrators would use SPF this would not be an issue. I was not aware about SPF until very recent and I must admit that it is a great idea to use. I have just created an SPF record yesterday. You can read more about SPF here: http://www.microsoft.com/mscorp/safety/content/technologies/senderid/wizard/ And here http://www.openspf.org/ As for now you could invest in a Barracuda. It makes a great job fighting spam. It is not that expensive and it is easy to use. http://www.barracudanetworks.com/ You can also download a free antispam program and make your own antispam "box". http://assp.sourceforge.net/ Br Steen

    We use MX Logic and have excellent results after battling with two other filters in the past. Look them up on the web, they are a little pricey but well worth it. The difference between their quarantine file and the quarantine files delivered by previous third party filters our company used in the past is night and day difference. Previous filters would allow the user to release in some instances 100's of spam messages a day, while MX logic does not even let them see that many questionable emails in their quarantine file. Makes you wonder were the other companies artificially raising our spam count or is MX Logic that much better. I hope this helps you out, search the web for spam filters you will find something you can work with.
