Spam FilterTable of ContentsImportant information regarding Veracity's new Spam filterVeracity Communications has installed anti-spam software on the email server. This software scans every message that comes in and evaluates the likelihood that it is spam based on a combination of numerous criteria. Messages that it rates 5 "hits" or above are considered high probability spam. Please note that this is an entirely automated process; no human reads your messages or receives reports about the messages you receive. What do I really need to know if I don’t have time to read the rest of this document?You will see some changes in your email for messages that the anti-spam software suspects may be spam. All messages that the system suspects are spam, weather low probability or high, are delivered to you normally. However, these messages will have the spam probability appended to the original subject line to alert you. Messages that are unlikely to be spam (your “real” email) will not be touched. What is spam?Spam is unsolicited mass email, or junk mail. Once your email address finds its way onto one spam mailing list, it is likely to be sold or distributed to owners of other lists at an alarming rate. Pretty soon, you can’t find your real email among the literally hundreds of junk email messages that arrive in your Inbox daily. About 70% of the email on the Internet is spam. What happens to my spam?Your spam is delivered to your mailbox. However, the subject line is altered to indicate the spam rating. In addition, the hidden Internet message header is tagged with information about the spam rating. The altered subject line allows you to easily scan your messages to find those that are likely to be spam. The tagged Internet message header allows you to create filters using Outlook’s Rules Wizard to automatically move suspected spam message to a separate mailbox or delete them altogether. How will the subject line appear on spam messages?The spam probability rating will be appended to the beginning of the subject line. For example: Original Subject: Free Junk!!! Modified Subject: [spam][5.4 hits] Free Junk!! How will the Internet message header be altered?Normally, you don’t see the Internet message header. However, this header is sometimes useful to find out where a message originated and the path it took to reach you, among other things. The Internet message header is not particularly readable to the uninitiated. To see the Internet headers, locate a message in your Inbox and double-click to open the message. From the View menu, select Options. If the message has received a spam rating by PureMessage, information about the spam rating, as well as the basis on which is was rated, will be inserted into the Internet headers. It might look something like this: X-Spam-Score: 15.668 (***************) DATE_IN_PAST_06_12, DOMAIN_RATIO, EXTRA_MPART_TYPE, HTML_90_100, HTML_IMAGE_ONLY_08, HTML_MESSAGE, MIME_HTML_MOSTLY, MPART_ALT_DIFF, PLING_QUERY, URIBL_AB_SURBL, URIBL_OB_SURBL, URIBL_SBL, URIBL_SC_SURBL, URIBL_WS_SURBL We are interested in the first part, which shows the probability. “X-Spam-Score: 15.668”. (The second part shows all the test criteria used to arrive at this rating, in a somewhat cryptic format.) Each test has a "score" associated with it. As the scores are tallied, the spam probability is found. How do I make a rule in iVeracity Web Mail to filter all spam messages to a junk folder?Coming soon... How do I make a rule in Outlook to filter all spam to a junk folder?In Outlook, go to Tools-> Rules and Alerts Click "New Rule" "Move messages with a specific word in the subject" The specific word you will add should be "[spam]". That is open-bracket, spam, close-bracket. The line below should let you pick what to do with those messages. I suggest moving them to the outlook "Junk" folder. What software does the iVeracity Spam Filter use?Postfix (Mail Delivery), Amavis (Mail Scanner), SpamAssassin (Spam Identifier), ClamAV (AntiVirus) |
