Technology includes:

Blacklisting maintains up-to-date lists of known spammers, compiled from anti-spam databases. This list grows daily and is updated automatically for each customer.
Keyword scanning methods include scoring systems for emails based on multiple criteria. If the email score exceeds defined thresholds, it is flagged as spam. We constantly monitor and update our keywords’ master library so you don’t have to.
Checksum technology tracks the number of times a particular message has appeared. If the message frequency exceeds threshold, it is blocked as spam.
Message authenticity check uses multiple algorithms to verify authenticity of a message. Some are simple checks such as “from address,” and others are more complex, relating to SMTP protocol.
Blacklists / Whitelists include Domains, IP’s, and email addresses that the customer wants Blacklisted or Whitelisted. Lists are maintained per user and per domain.
Rate controls are used to stop denial of service attacks and other service attacks.

Antivirus Technology includes:

Anti-virus protection is a built-in feature of Upstream Spam Filtering. Updates are posted hourly to ensure the latest virus definitions are in place.
File type attachment blocking stops known malicious file types, such as VB script, from entering your network through emails. Attachments are also scanned using the built-in anti-virus protection.

FAQs

Q: What is an MX Record? An MX Record or "Mail Exchange" record tells mail servers around the world where to point your Domain Names mail to. An MX Record is always located on your primary DNS (domain name service) server which is located at your site, an ISP, a Hosting Company, your District site or at your centralized State Agency.

Q: How do I change my MX Record? Your domain administrator is able to modify your DNS server MX records. Upstream engineers are available to assist your domain administrator in making the change.

Q: How do users contact Upstream for support? Upstream Spam Filtering comes with toll-free Technical Support. Just call Upstream’s Support Team at (888) 826-4368 Monday-Friday, 6 AM-5 PM (PST) or email us at support@tcnoc.com.

Q: What notifications will you send to our email users? Initially, your users will receive no messages from us at all. Upstream Spam Filtering is a transparent filtering service. Besides seeing a huge reduction in inbox Spam, your users will see two changes in their email.
Email messages identified by Upstream Spam Filtering as probable Spam, but not 100% sure Spam, are delivered to the user inbox with [BULK] or [QUAR] prefixed to the subject line. [QUAR] messages score a higher Spam probability than [BULK] messages.

Q: How do users configure personal settings? Users have the OPTION of logging into the server and managing personal settings for their user account. Each user can create custom white and black lists, turn on/off spam filtering and enable / disable Quarantine. Quarantine ENABLED causes quarantined mail to not be delivered to their inbox. It is stored on our server in a password protected area where the user can retrieve it at their leisure. Each user receives daily or weekly notices (their choice) that they have Quarantined email to be reviewed.
Most users prefer to receive their [QUAR] mail in their inbox, and not have it stored for later retrieval.
Adding a simple filter to your email reader to store [BULK] and [QUAR] flagged messages to a separate folder is an easy and effective way to manage these messages for later review when time permits.
