How Does Virus Scanning Work?
When an email arrives on the mail server:
- The message is received by the mail system.
- Attachments are scanned for known malware signatures.
- Suspicious or infected files are identified.
- Appropriate action is taken according to the server’s security policies.
This process takes place automatically and does not require any action from the mailbox owner.
Antivirus Software Used
Email attachments are scanned using:
ClamAV
ClamAV is a widely used open-source antivirus engine designed to detect:
- Viruses
- Trojans
- Worms
- Malware
- Malicious scripts
- Other potentially harmful files
The software is continuously updated with new virus definitions to help identify emerging threats.
Benefits of Server-Side Scanning
Server-side virus scanning provides several advantages:
- Protection before messages reach the mailbox.
- Reduced risk of opening infected attachments.
- Automatic scanning without additional software requirements.
- Improved email security for all users.
Important Notes
Although antivirus scanning significantly improves email security, no antivirus solution can guarantee 100% detection of all threats.
For maximum protection, it is recommended to:
- Keep your operating system updated.
- Use antivirus software on your local device.
- Avoid opening unexpected attachments.
- Verify the sender before opening files or clicking links.
Summary
All incoming emails are automatically scanned for viruses and malware at the server level using ClamAV, an open-source antivirus solution. This helps detect potentially harmful attachments before they reach your mailbox and provides an additional layer of email security.
