You can now set the default script sender address

If you install a script that sends mail, that script should let you choose the address it sends from. Unfortunately, some scripts don’t offer that feature, instead using a default sender address that on our systems looked like “From:” until now.

The inability of these scripts to specify a sender address has become more of a problem as email reputation and security systems like DKIM are deployed.

To help with this, we’ve enhanced our email system to allow you to specify the sender address these scripts use. The “How can I change the default address?” section of our page about script addresses has more details.

By the way, if you use a script like this and you don’t choose an address, it will default to the slightly different “From:” from now on. But we recommend that anyone who uses these kinds of scripts choose a real address instead, which will ensure other people see only your own domain name.
