I've seen similar- check both the sender and envelope addresses in the 
original message (you may have to ask for a sample). Sometimes, the sender 
will be 'sender at domain.com' but the outgoing MTA will slip in 
'sender at other.domain.com', which then isn't a list member. Or the reverse- 
user and list have 'sender at other.domain.com' and the MTA rewrites that as 
'sender at domain.com'.
