CybrHost does not block any email to your mail domain. The Internet is flooded with soliciting E-mail messages distributed to millions of E-mail addresses. These messages are known as "spam". Spammers fill your mailboxes with a huge amount of unwanted messages, not only overloading the Internet and your Server resources, but making mail retrieval very slow and difficult for you. To prevent unauthorized spam CybrHost employs the five following methods to filter offending email:
1. Blacklisted IP Addresses
2. Blacklisting IP Domains
3. Banned Header Lines
4. Banned Body Lines
5. RealTime Blackhole Lists (RBL)
These methods nearly eliminate all spam flowing to you (around 90-percent.). The black-hole account in your mail domain is where our messaging system delivers spam identified (unsolicited) email. Acceptable client email may find its' way into this account if the sending host has been blacklisted by multiple RBLs. These misdirected messages are called false positive email.
For a small monthly fee CybrHost now offers an additional level of UCE filtering that will virtually eliminate 99-percent of all spam. For each message, SpamCatcher applies checks of its four spam detection engines:
- SpamBulk Engine
Is the message or similar messages sent in bulk?
- SpamRepute Engine
Do most people want the message?
- SpamContent Engine
Will most people consider the message offensive?
- SpamTricks Engine
Is the message formatted or sent to bypass anti-spam rules or to be economical for spammers?
For every message, the four engines check over a thousand rules and several locally cached
databases. SpamCatcher also creates a fingerprint ID for every e-mail message and compares
it to existing fingerprints in its databases. The Mailshell database is updated every eight hours. The
results of all of the engines are combined using SpamScore, a proprietary Bayesian
statistical formula, into one final spam probability score.
Since spam constantly evolves, the Mailshell SpamLabs continuously collects and analyzes millions of new spam and legitimate messages and user feedback to tune the rules and databases and adjust the weighting of existing rules.
The SpamCatcher, when combined with our IP- and RBL-based UCE system virtually eliminates 99-percent of all spam messages.
Is your mail tagged as UCE (Spam)?
To see if your mail is being tagged as UCE send an email to mailtest@cybrhost.net.
You will receive a response stating the status of your message.
Receiving False Positive Messages
If you receive spam outside of the black-hole account, copy the full headers, and paste that information which includes the sending IP address, into a forwarded copy of the original email and send it to:
kill-spam@cybrhost.net
If you receive good client email in the black-hole account, copy the full headers, paste that information which includes the sending IP address back into a forwarded copy of the original email and send it to:
blacklist-admin@cybrhost.net
How do you obtain the full headers?
Outlook Express
To get the header information that 'came' with the email, highlight the email in the box and 'right click' on it. Down at the bottom of that popup menu, left click on "Options". This displays the 'full header information' with the IP number and other information needed.
Eudora
In Eudora in order to display full headers you first double-click on the message in question so that it opens. When you do this, it presents the body of the message with an editable subject bar at the top. Left of the subject bar are four action buttons. Place your mouse arrow over the third button (from left to right), and it presents to you the phrase...."Show All Headers." Click on it and the regular header at the top of your message window below expands into the full header.
CommuniGate Pro Web Mail
To display the full headers when using the CommuniGate Pro web interface click on the
 located in the upper right-hand corner of the address block. A new page will appear
displaying the full headers. Copy this information, close the window, and press Forward. The mail sending
screen will appear. Paste the header, previously copied, into the message screen and above "--- the forwarded message follows ---."
Send the email to either of the addresses above.
No Spam Policy: Acceptable Use Policy on UCE (Unsolicited Commerce Email)
Background
We at CybrHost do not like spam! Accordingly, we added anti-spamming software to our server to eliminate it, and we enabled that capability to our clients. Personally and as a corporate entity we have an no tolerance philosophy with respect to spam. This expanded UCE section intends to reflect that philosophy and to aid our clients in complying to protect themselves, our other clients, CybrHost, and Internet users at large. Our clients are expected to have an understanding of what constitutes spam. If they do not, they are expected to research the topic on line. A good starting place is http://spam.abuse.net/. Please contact us if you have any questions before embarking on an email advertising campaign. Violators of this philosophy will be treated harshly.
Policy Guidance
Spamming, the sending of mass unsolicited email from or through a CybrHost server or using an email address that is maintained on a CybrHost machine, is STRICTLY prohibited. Clients are also in violation of this provision if they engage in spamming using the service of another ISP or IPP, but reference in the spam a Web site hosted on a CybrHost server or CybrHost email address, or if they sell or distribute software on their web site that facilitates spamming. Violators will be assessed a minimum $200.00 fine and will face immediate suspension. CybrHost will be the sole arbiter as to what constitutes a violation of this provision.
Should CybrHost receive a spam complaint, a notice is sent to the Webmaster of the domain giving 48 hours to respond with an explanation and, the domain's mail IP address will be changed. If no response is received, the site is taken off line until an acceptable response is received and the incident is cleared. CybrHost must not allow any single site to effect a blacklist of the CybrHost mail servers which would be detrimental to our clients.
Important Note
Please keep in mind that "email is intended for 1:1 communication, not broadcast." Sending unsolicited mail messages, including the sending of "junk mail" or other advertising material, to individuals who did not specifically request such material, who were not previous customers of the Client or with whom the Client does not have an existing business relationship is spamming and is prohibited.
Verifiable Opt-In List
Proof that an email address did in fact opt-in can be a log excerpt or a copy of the returned, e-mailed confirmation. There must be proof of a two-way, secure confirmation. This must include IPs and datestamps for two stages - both a signup and a confirmation. Here are some links that will serve as a starting place if you want to send out the same email to a large number of addressees.
