Over the past year or two we have seen new types of spam to evolve. In some cases spamers come up with some pretty interesting ways of getting their message delivered. However there is something they have in common. It's quantity - the more spam they send the more profits they can expect. That's exactly where XWall CCS enters the picture. The CCS is based on a message body checksum. All XWalls with CCS send the checksums of the incoming messages to the central server and it keeps track of the bad guys. In turn the central server tells XWall how many times it has seen this message in the past couple hours. if that above your limit the message is fagged as spam. The filter has practically no false positives for messages sent by individuals. You may need to exclude some email newsletters with a larger circulation. 

From Viagra Sales

Lately we received some call from users asking how to block from display names like "Viagra Sales" Here are some examples how to deal with the issue. But first check if the message is excluded (global or white list) in XWall. you can see that in the header info, example -> Xwall exclude: global email in that case you need to fix this issue first.

a) Viagra Spam: The Viagra spam can be blocked using Header blocking, but much better is to enable the blocking of self-sending spam. See http://www.dataenter.co.at/doc/xwall_faq.htm#KBXW057


b) Header blocking: XWall searches the string inside the data. This means "From:viagra" is the correct one, "From:*viagra" or "From:viagra*" will not necessarily do what someone would expect.

c) DKIM / DomainKeys: A user asked why XWall doesn't add DKIM to the message when the message is already signed.

A general rule in XWall is, that any message inbound or outbound that is signed or crypted is not touched in any way, because this may break the seal.

One way around this is to let XWall sign outgoing messages, because then XWall know how to add both DKIM and SMIME.
