[MM3-users] How to get Hyperkitty to show actual sender e-mail addresses?

Hi,

I'd like to show actual sender e-mail addresses (basically to block spammers sending to a list that is used as a contact address, so it has no moderation for non-member postings). Hyperkitty just show the display name, which not very informative.

Is there a setting to change this behavior? I did not find any using internet search and sifting through the various config files, but I could easily have missed something.

Cheers, Hans-Martin
