Imagine you have an internal system that sends outbound emails from accounting@yourcompany.com. Your goal is to change the sender's address accounting@yourcompany.com to reminders@yourcompany.com. This is where the sender transformation rule comes into play: it can modify the sender's email address for outbound messages.
Use the following method to specify sender transformers:
accounting@yourcompany.com), and the second value is for the new address (reminder@yourcompany.com).$any_user to specify a wildcard.
$any_user@accounting.example.com|accounting@example.com
In this case, the domain name of any incoming email using the domain accounting.example.com will replaced by accounting@example.com
Original Sender: no-reply@accounting.example.com
Modified Sender: accounting@example.com
$any_user@accounting.example.com|$any_user@example.com
In this example, the user part in the email will not be modified.
Original Sender: no-reply@accounting.example.com
Modified Sender: no-reply@example.com
