Mail Security for Microsoft Exchange

Issue/Introduction

 

Resolution

Mail Security lets you specify the users and groups to which the rule applies. You can also specify which users and groups are exceptions to the rule.

Note:

This feature is not available for the Edge Server role.

You can select groups from Active Directory. You can also add users based on SMTP addresses.

Table: Supported SMTP address formats shows the SMTP address formats that Mail Security supports.

Table: Supported SMTP address formats

Address

Example

@<domain name>

@symantecdomain.com

*@<domain name>

*@symantecdomain.com

<name>@<domain name>

[email protected]

<name>@<subdomain.domain name>

[email protected]

Note:

Using regular expressions for SMTP addresses is not supported

When you use the address formats from the table above, sub-domains are automatically supported. For example, when you use the address format <name>@<domain name>, Mail Security will support [email protected], as well as [email protected]

If you do not specify users, the rule applies to all senders and recipients.

If you are using Exchange 2007, and you want to specify a user or group whose domain is not in the Exchange server domain, specify the domain name in the Internal Domains list.

If you are using Exchange 2013/2016, and you want to specify a user or group whose domain is not in the Exchange server domain, specify the domain name in the Internal Domains list.

Note:

You can select any Active Directory group except the Users group. Adding the Users group to Active Directory Groups list results in unintended behavior. On Exchange 2010 mailbox server role, for content filtering rules based on Active Directory group, you must add SMSMSE service account user (RBAC user) to the SMSMSE Admins Active Directory group.
