Mailing list settings

[Mark Doliner]

FYI I'm changing this list back to reject mail from people not on the
list instead of holding it.  For some reason this list gets between 30
and 50 spam emails a day, and I'm not willing to scan through the
subjects/senders of all of them every day for such a low traffic list.
 If anyone else wants to then Luke or Sean or I can add you as the
list admin and you can change the setting.
