Why isn't the user's e-mail address used when sending a message to another Medius user?

Prior to release R53, e-mail messages from MediusFlow were sent using users' e-mail addresses. This caused some spam filters to incorrectly classify such messages as spam. In R53, we introduced the antispoofing mechanism. As a result, all messages are now sent from a standard e-mail address: info@email.mediusflow.com.

This solved the spam filters problem, but it also means that you cannot respond to an email from info@email.mediusflow.com and expect the user who e.g. mentioned you in a comment to receive the response.

It is possible to turn antispoofing  off, restoring the functionality from before R53. To do this, go to the Email Provider Configuration administration page and set the Antispoofing option to No.
