Mail Anti-Virus

This section provides the description and settings of eScan's Mail Anti-Virus for scanning of emails.


Contents


Description

Mail Anti-Virus is the second module of the eScan for ISS. This module scans all incoming and outgoing e-mails for viruses, spyware, adware, and other malicious objects. It helps you send virus warnings to client computers on the Mail Anti Virus activities. By default, Mail Anti Virus scans only the incoming e mails and attachments, but you can configure it to scan outgoing e-mails and attachments as well. Moreover, it helps you notify the sender or system administrator, whenever you receive an infected e-mail or attachment.

 

 

This page provides you with options required for configuring the module. You can configure the settings from the following 2 sections:

Configuration

This section displays the following information.

- Mail Anti-Virus Status : It displays the status of whether Mail Anti-Virus module is started or stopped.

- Action : It displays the type of action set in the Mail Anti-Virus module.


Start/Stop: Click an appropriate option to enable or disable Mail Anti-Virus module.


Settings: When you click this button, the Mail Anti-Virus Settings window appears. On the Mail Anti-Virus Settings window, you have two tabs – Scan Options and Archiving which are as follows:

Note: On below the screen of all the tabs contains four buttons — Default, OK, Cancel, and Apply, which you have to use after configuring the settings based on your requirement.

  • Scan Options

This tab allows you to select the e-mails to be scanned and action that should be performed when a security threat is encountered during a scan operation.

 

 

This tab helps you configure the following settings:

- Block Attachments Types: This section provides you with a pre-defined list of file types that are often used by virus writers to embed viruses. Any e mail attachment having an extension included in this list will be blocked or deleted by eScan at the gateway level. You can add file extensions to this list as per your requirement. As a best practice, you should avoid deleting the file extensions that are present in the Block Attachments Types list by default. You can also configure advanced settings required to scan e mails for malicious code.

--> Advanced: You can click this button to open the Advanced Scan Options dialog box. This dialog box helps you configure the following advanced scanning options:

 >> Delete all Attachment in eMail if disinfection is not possible: Select this check box if you want to delete all the e mail attachments that cannot be cleaned.

 >> Delete entire eMail if disinfection is not possible: [Default] Select this check box if you want to delete the entire e mail if any attachment cannot be cleaned.

 >> Delete entire eMail if any virus is found: Select this check box if you want to delete the entire e mail if any virus is found in the email or the attachment is infected.

 >> Quarantine blocked Attachments: [Default] Select this check box if you want to quarantine the attachment if it has an extension that is blocked by eScan.

 >> Delete entire eMail if any blocked attachment is found: [Default] Select this check box if you want to delete an e mail if it contains an attachment with an extension type that is blocked by eScan.

 >> Quarantine eMail if attachments are not scanned: Select this check box if you want to quarantine an entire e mail if it contains an attachment that is not scanned by Mail Anti Virus.

 >> Quarantine Attachments if they are not scanned: Select this check box if you want to quarantine attachments that are not scanned by Mail Anti Virus.

 >> Exclude Attachments (Whitelist): This list is empty by default. You can add file names and file extensions that should not be blocked by eScan. You can also configure eScan to allow specific files even though if the file type is blocked. For example, if you have listed *.PIF in the list of blocked attachments and you need to allow an attachment with the name ABC, you can add Abc.pif to the Exclude Attachments list. Add *.PIF files in this section will allow all *.PIF to be delivered. MicroWorld recommends you to add the entire file name like ABCD.PIF.


- Action: This section helps you configure the actions to be performed on infected e mails.

--> Disinfect: [Default] Click this option if you want Mail Anti-Virus to disinfect infected e mails or attachments.

--> Delete: Click this option if you want Mail Anti-Virus to delete infected e mails or attachments.

--> Quarantine Infected Files: [Default] Select this check box if you want Mail Anti-Virus to quarantine infected e mails or attachments. The default path for storing quarantined e mails or attachments is C:\Program Files\eScan\QUARANT. However, you can specify a different path for storing quarantined files, if required.


- Port Settings for eMail: You can also specify the ports for incoming and outgoing e mails, so that eScan can scan the e mails sent or received through those ports.

--> Outgoing Mail (SMTP): [Default: 25] You need to specify a port number for SMTP.
