I have setup a moderated mailing list in Mercury 4.91 with 2 moderators. Listmembers are able to send to the list and should get their own replies. I just tested the list with my member address and Mercury started working the list. And than came the strange and buggy part: The sender was not my member address The From address was formed of the 2 moderators email address. It created a total mess.

I can't see any wrong settings in my list configuration which could cause such behavior. I have 2 lists with 130/150 users.
Years ago with Mercury 4.01 I did not have such problem.
Any pointers would be appreciated.
