Perl 5.16.x and majordomo restrict_post

Hi all

 	We recently tested perl 5.16.0 with a test majordomo mailing list. 
In the past, we used restrict_post to restrict postings to a mailing list 
to just the subscribers.  Interestingly enough, upon going to 5.16.0, this 
feaature seems to have broken and emails posted to the mailing list not 
only do not make it, they get silently discardrd.  Here's what the debug 
output from resend looks like:

addr_match: comparing <[email protected]> against [email protected]
addr_match: comparing <[email protected]> against [email protected]
is_list_member: exit 0
/home/majordomo/resend: sender check: '   Non-member submission from 
[ <[email protected]>] '
/home/majordomo/resend: parse_body: enter
/home/majordomo/resend: parse_body: exiting with ''
/home/majordomo/resend: bounce enter
/home/majordomo/resend: bounce exiting

According to this, we have have no match, but this ought to have worked. 
I haven't yet pinpointed the bug but has anyone else seen this?

Thanks,

wfms
