Bharat Fritz Werner (BFW)-Mail Scanner

The company faced the issue of a large amount of spam and viruses that hogged

costly bandwidth. Therefore, the in-house IT team developed and implemented an

Open Source solution for reducing spam and viruses, MailScanner. The solution

provides the engine used to scan incoming email and detect security attacks,

viruses and spam. Email is accepted and delivered to an incoming queue

directory. Mail Scanner processes the waiting messages and then delivers the

cleaned messages to the outgoing queue directory, where they are picked up and

delivered normally. Only after the messages are delivered to the outgoing queue

directory are they deleted from the incoming spool directory. This ensures that

no mail is lost, even in the event of unexpected power loss, as the system

always has a copy of all messages. MailScanner can be configured to use one or

more of 26 commercial or Open Source virus scanners. The application examines

the file name and file types of all email attachments against site configurable

rule sets. Virtually any type or name of attachments can be blocked or passed,

based on how MailScanner has been configured.
