Not sure what you are asking. Are clients from dibu.com using comsec.net to send there email? http://www.dnsstuff.com/tools/ptr.ch?ip=dibu.com reports that there isn't any ptr records for dibu.com. If dibu.com is one of your hosted email domains then I would think they too would need there ptr/sfp records established. AOL will no longer accept mail to them from servers without a valid ptr record.
No, our customers are aclc.org. They are having problems sending to dibu.com .
