I would check 2 things:

#1: The sending address in Roundcube is a valid user or alias. It's 
possible for a user to create an identity in Roundcube that doesn't 
match an actual address on the server.

#2: The sending address hasn't been added to a reject list somewhere 
(ie: Network Services -> Email -> Advanced tab or AV-Spam -> 
SpamAssassin -> Blacklist from)

That's assuming of course that the DNS entries are properly configured 
for the domain.  Since your other domain users don't report problems 
that's probably OK but if this is your only webmail user then you need 
to look at what that box is seeing differently than your users.
