SMTP - Action 1

What can I do here?

Use the Rewriting Rules to rewrite Sender and Recipient headers in emails.

The left field is a match field for the original header. The right field is for the rewritten header.

You can also rewrite other email headers:

• Field - the name of the header
• Contents - the name of the original field and the replacement field.

You can use wildcards and regular expressions to specify and rewrite the Sender and Recipient headers, and the Field and Contents headers.
