Contact Owner Mailto Issue

This came in via the HWP site from Professor Pinker:

Dear Open Scholar folks,

There seems to be a strange and unhelpful change in the "Mail to" feature of my OpenScholar site -- messages are marked as coming from "", regardless of the sender. This has two problems: when scanning my Inbox, I can no longer see who the message is from, and the "Reply" function is now useless.

Many thanks for your help with this,
