Why do my scripts send e-mail from an address ending with @tigertech.net?

This page is showing a generic answer. To see a more
specific answer, please type your domain name below:

Some scripts may appear to send e-mail from the address example.com@tigertech.net. This happens if you use a script that sends mail without properly specifying the "Return-Path" address (also called the "envelope sender" address).

A message's Return-Path is separate from the "From:" address. These two addresses are used for different purposes:

If your script doesn't manually specify the Return-Path address, our system creates one for you by combining your domain name with "@tigertech.net" (such as example.com@tigertech.net). Our mail system will forward any messages sent to example.com@tigertech.net to the administrative contact for the account, ensuring that you receive any bounced messages.

How do I avoid a generic Return-Path address?

If you don't want a "generic" Return-Path, your script can control it when sending an e-mail message:
