just launched a second exchange 2003 ent. server and moved mailbox's to phase out existing/outgrown exchange. users cannot send mail to aol, comcast, bellsouth, and various others but domain mail and gmail, hotmail, yahoo, work fine in and out. any ideas why I'm getting message "non deliverable", timed out, or delayed errors. can't see why gmail and others would work fine but not aol, etc.
