Hello, I am having a problem sending and replying to a particular domain. This only happens when we use the iPhones. If I send a message to multiple e-mail addresses the only ones that come back are from only the one domain. Below is the errors message that I get. The question is, is this a problem with my mail server or is it on the receiving email server. Your message did not reach some or all of the intended recipients. Subject: Test message Sent: 6/1/2010 2:10 PM The following recipient(s) could not be reached: Mike M on 6/1/2010 2:16 PM You do not have permission to send to this recipient. For assistance, contact your system administrator. <mymailserver.com #5.7.1 smtp;554 5.7.1 The message from (<administrator@mymailserverdomain.com>) with the subject of (Test message) matches a profile the Internet community may consider spam.

You'll have to contact the admin of that organization to find out why. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
