Hello everyone, hopefully someone can help me with dilemma I have There are 4 boxes in play total. Aix RHEL Centos Exchange Centos is configured to send mail via Exchange server at a hosted location by use of msmtp (it replaced sendmail all together on this box). I would like Aix and RHEL boxes to send mail through centos, which then would deliver to exchange. For various reasons - both aix and rhel cannot send directly to exchange like centos. Is this something that can be accomplished? Thanks everyone
