Where is your spam coming from?

Did you ever wonder who sent you that spam? ESATInformer reports show the country of the spam server. Its a very interesting report. Seeing the foreign country listing helps the end user to spot spam and understand that his best friends address has been spoofed...Unless the friend did move to Korea last night!

(PRWEB) September 16, 2004 -- ESTAInformer 1.15 tells you more about your email and spam situation. The user gets one or more emails a day reporting all the blocked message. The sender and subjects are sorted by spam filter counts. Messages that got caught by only one filter are on top of the list others follow. Each sender includes the server location by country. You may see joe@us-domain.com (KR). The (KR) implies that Joe sent the message from a server in Korea. Would you best buddy do that?

The ESATInformer admin report ranks the sending countries showing spam and non-spam mail counts. With this information provided you may choose to block entire spam countries. The admin report contains a lot of other important information. It shows who sends and receives all the spam and mail. Mail flow charts allow easy viewing of message counts per hour incoming and outgoing. This information allows the admin to maintain optimal spam filter settings.

The information ESATInformer compiles in the easy to read email reports are extracted from the XWall spam filter and mail control system logs. XWall just added new filters to the lineup. To protect your users from all that spam, XWall implemented greylist filtering. The effectiveness of that filter will raise an eyebrow or two. Once the greylisting is turned on in XWall its not uncommon for users to panic. The filter is responsible for a dramatic reduction in spam. Some users think the mail system stopped delivering. It just stops delivering spam. The user can check the detailed email report ESATInformer mails to each user at least daily. Best of all, the XWall /ESAT combo keeps all that spam out of your Exchange server, or most other SMTP servers. There is no need to expand the server just to keep piling up the ever-increasing spam in Exchange.

The XWall greylisting filter is simple in nature. SMTP mail was considered unreliable - even before the age of spam. The RFC (e-mail standard) protocol requires the sending server to resend any messages not successfully delivered. A mail server will attempt redelivery of bounced message after 10-20 minutes. The spammers however use email differently. Throughput per hour is what counts for them. They dont waste time retrying a connection. So some smart people had a great idea. Why not deny delivery at the first attempt? Then, when the message arrives a second time, it is allowed to pass. This is a truly innovative idea with great results and very few false positives. XWall 3.31 features a greylist filter. XWall keeps a record of all unique messages by sender, recipient and server. This record is called a triplet. Messages not seen before will be rejected sending a temporary message handling error. When the triplet shows up a second time it will be accepted. Some non-standard mail delivery agents sometimes used by newsletters can be excluded if they dont resend. The ESATInformer report allows the user to spot these situations.
