And that is the entire issue. acceptable_aliases and 
require_explicit_destination have nothing to do with this.

All that does is avoid the message's being held for "implicit 
destination" it doesn't bypass other checks.

There are a few of choices.

You can set Privacy options... -> Sender filters -> 
generic_nonmember_action to Accept in order to accept posts from any 
nonmember, but you may not want that.

You can ensure that everyone sending mail to info at lf.me is a member of 
the comm at lists.lf.me list.

You can make use of the fact that mailman considers a post to be from a 
member if any of the From:, Reply-To: Sender: or envelope sender 
addresses is a list member. Posts from google groups generally have no 
Sender: header, and the envelope sender is something like 
'info+bncbcn2p7unuujrbfxhspsakgqe7gew6fa at googlegroups.com' where the 
'bncbcn2p7unuujrbfxhspsakgqe7gew6fa' may not be constant. However, 
messages from Google Groups have a

Reply-To: groupname at googlegroups.com

header. If that address is a member of your list, it should be OK. You 
say info at lf.me is a member of your list. Is that an address you control 
which forwards to the google group?. If so, you want to make 
groupname at googlegroups.com a member of your list set to nomail. If in 
fact by info at lf.me you mean the actual groupname at googlegroups.com 
address, then I don't know what the problem is.
