Qemailserver spam checker

Qemailserver is a popular open-source email server software that provides a robust and customizable solution for managing email services. When it comes to spam checking, Qemailserver offers several options to help filter out unwanted emails. Here are some of the spam checking features available in Qemailserver:

  1. SpamAssassin: Qemailserver comes with SpamAssassin, a popular open-source spam filtering system. SpamAssassin uses a combination of rules, Bayesian filtering, and other techniques to identify and block spam emails.
  2. ClamAV: Qemailserver also integrates with ClamAV, a popular open-source antivirus engine that scans emails for malware and viruses. ClamAV can help detect and block spam emails that contain malicious attachments or code.
  3. Greylisting: Qemailserver supports greylisting, a technique that temporarily blocks unknown senders to prevent spam emails from reaching your inbox. Greylisting can help reduce the amount of spam emails that reach your inbox.
  4. RBL (Real-time Blackhole List) checks: Qemailserver can check RBL lists, which are databases of known spam senders. By checking these lists, Qemailserver can block emails from known spam senders.
  5. Custom spam filtering rules: Qemailserver allows administrators to create custom spam filtering rules using regular expressions, IP addresses, and other criteria. This allows for fine-grained control over spam filtering and can help block specific types of spam emails.
  6. Bayesian filtering: Qemailserver uses Bayesian filtering, which is a statistical method that analyzes the content of emails to determine whether they are spam or not. Bayesian filtering can help improve the accuracy of spam detection over time.
  7. Spam scoring: Qemailserver assigns a spam score to each email, which is based on various factors such as the sender's IP address, the email's content, and the email's headers. This allows administrators to set thresholds for spam detection and block emails with high spam scores.
