One of our other companies, for whom I didn't set up the Exchange server, don't have control over, but have to tell them how to fix problems, is getting the following NDR when they send to or reply to e-mail at one specific domain.
There was a SMTP communication problem with the recipient's email server. Please contact your system administrator. <server.domain.local #5.5.0 smtp;550-Verification failed for <[EMAIL PROTECTED]>> The receiving domain the e-mail is being sent to is using Exim mail server software. After doing some research I am fairly certain the NDR is being caused by the Exchange server returning server.domain.local rather than mail.domain.com. But I haven't figured out how to get Exchange to return the correct name. How do I get the Exchange server to return the correct DNS name? ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja ~
