Yes, it's not always so easy as it seems, however it's easy doable with source-routing and binding local outgoing IP is the easiest way for msmtp (and other programs) to help with that. so, while binding to source IP will not cause packets to go from different interface by itself, it's needed for it to be done. -- Matus UHLAR - fantomas, uh...@fantomas.sk ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
