Aliases

Forcepoint Email Security Cloud can rewrite email addresses as email enters and leaves your system. Aliases must be to and from domains associated with your Forcepoint Email Security Cloud policies. Aliases let you rewrite email addresses both inbound from the Internet and outbound to the Internet. When an alias has been applied, email passes through the policy for the new address. Addresses in the SMTP envelope and in those header fields defined in the standard Internet message format (as defined in RFC 2822) are rewritten.

An alias can apply both inbound and outbound. In this case, there is a one-to-one mapping of an internal address to an external address and vice-versa. This is often called masquerading an address.

An outbound-only alias is also a one-to-one mapping.

An inbound-only alias can be a one-to-one or a one-to-many mapping (a distribution list). To specify a distribution list, separate email addresses with commas.

If an alias is neither inbound nor outbound, it is a disabled record.

To view the aliases that have been configured for your system, select Email > Settings > Aliases.

To search for all aliases in the system, enter an asterisk in the Email address field, check both the Inbound and Outbound check boxes, then click Search.

To narrow the list to specific entries, enter search criteria in the Email address field, such as "*john*". Wildcards are supported.
