See below. Does OpenSMTPD support SRS yet? Or can I just never receive
email from people anymore with OpenSMTPD?

Hi IDA User,

Unfortunately we can not communicate with you by email because your
message forwarding has been set up incorrectly. Our messages are being
forwarded to gmail.com without changing the "From:" field, but gmail
rejects them because your server may not send message on our behalf.
Only our mail servers may send messages from Hex-Rays.

To fix the problem the SRS mechanism should be implemented:

https://en.wikipedia.org/wiki/Sender_Rewriting_Scheme

Please note that this is a one time message.
