VPOP3 Email Server for Windows 95/98/ME/NT/2000/XP
Virus Scanning with VPOP3
A commonly requested facility is the ability to scan incoming and/or outgoing attachments for viruses.
Most standard virus scanners are not able to detect viruses in attachments which pass through VPOP3. This is because they
are encoded using either BASE64 or UUENCODING which most virus scanners do not understand.
Because of this, VPOP3 has been created with 'hooks' to allow the integration of virus scanners into their operation.
The most common methods (in descending ease of installation) are:
- From VPOP3 2.0.0 onwards, VPOP3 supports avast! for VPOP3. This is a very competitively
priced product based on the avast! antivirus solution.
- From VPOP3 1.4.1 onwards, VPOP3 has integrated support to work with
Sophos Antivirus to scan incoming and outgoing messages for viruses.
- Microworld Technologies Inc. have developed a customised anti-virus and content security
product called MailScan for VPOP3 which can
scan incoming and outbound emails (both POP3 and SMTP) on a real-time basis before they are delivered to the email
clients or servers on your network.
- The VPOP3 Plugins Pack contains a utility called VPOP3DECODE which can extract
attachments from both incoming and outbound messages and pass them to most virus scanners for scanning, and then it
will redirect infected messages to an administrator. (This will work with most virus scanners,
so will need some configuration to make it work with your particular virus scanner)
