Address Masquerading

User's Address Masquerading allows system administrators to configure IMail to replace the domain portion of an email address in the headers of messages as they are received by the SMTP Service. After messages are accepted for delivery by SMTP the system checks the headers of the message for any values listed in the Address Masquerading settings. If a match is found then that header line is rewritten with the value specified.

The following header lines are checked and updated if a match is found.

From
Sender
Reply-To
To
CC
Disposition-Notification-To
Return-Receipt-To

Usage Example
