How does UD Anti-Spam protect my mailbox?
Incoming mail is analysed on the server before it reaches your inbox. Junk and suspicious messages can be quarantined so you download legitimate mail more safely and reduce clutter and malicious links.
Stop spam emails from reaching your mailbox
UD’s powerful Anti-Spam Service incorporates Intelligent Identification Function which stands it out from similar services in the market. With information from data analysis, we scan all incoming emails on server level and quarantine junk emails which may interfere your daily work. This not only allows you to download emails in the most secure way but also ensures your Internet traffic will not be affected. The operation interface for each individual account is user friendly as well. You may set up your own Blacklist or Whitelist to optimize the filtering function.
UD Anti-Spam filters junk email at the server using intelligent identification and user-controlled blacklists/whitelists, so your team spends less time on spam and reduces exposure to phishing and malware-infected messages, without delaying normal mail.
Eliminate chances to receive emails with virus or scam phishing emails
Save time on handling influx of advertising emails
Prevent unnecessary information to occupy storage and drag down download speed

The system will automatically select and add the junk email lists to the system from other users, which could provide better and more comprehensive protection to all users.
Daily Spam Quarantine Summary Report will be sent to every user. Users can manage any spam or non-spam emails immediately.
Users can manage quarantined emails by simply deleting, delivering or whitelisting them.
Users can add permitted email addresses to Whitelist so that those emails can be delivered to your mailbox directly without scanning. At the same time, users can add email addresses to Blacklist so that any email sent from blacklisted addresses will be not delivered.
