MailGate Support Issues

Q. How do I set up the Virus Scanner with my anti-virus software?
A. If you are using Sophos Anti-Virus, the FAQ here explains what you need to do. If you're not using Sophos, the following instructions apply:

When using anti-virus software on the machine MailGate is installed on, you must make sure that your anti-virus software is configured so that the following directories are not scanned:
  1. C:\Program Files\Mailgate\log
  2. C:\Program Files\Mailgate\mailbox
  3. C:\Program Files\Mailgate\queue
The reasons for this are as follows:
  1. If an infected file is found in the log directory (if you have full POP logging enabled and the e-mail data is logged), this could lock up the log file and prevent MailGate from writing to it.

  2. If an infected file is found in a mailbox directory, this could lock the mailbox and prevent the user from collecting their mail, and could also prevent MailGate from delivering to the mailbox.

  3. If an infected file is found in a file in the queue, this could lock the file (or delete it), and could cause MailGate problems processing messages, leaving other routing components in the queue.
If you don't have the Virus Scanner Extension operating, and you exclude these directories from being scanned, please be aware that viruses will be able to pass through MailGate undetected. For this reason we strongly recommend using the Virus Scanner Extension together with your anti-virus software.

How the Virus Scanner Extension operates
Before messages get to the queue for processing (and before your anti-virus software can check them), the extension decodes attachments - providing extra security by increasing the chance of detecting viruses.

The extension places the attachments in a quarantine area, your anti-virus software is then initiated and the extension handles what happens to the file, whether or not it is infected. If a virus-infected file is found, the administrator and intended-recipient are notified that the e-mail contained a virus. A lot of development work has gone into making the decoding of attachments as accurate as possible.
