Exchange Server Refusing to Send/Receive via SMTP
Posted on 2006-07-10
I have a new-build Exchange Server, to which I have migrated by previous SBS2003 mailboxes and AD, via joining it to the domain, promoting to DC, and then seizing the Op master roles etc and restoring the mailboxes. Mailbox access and local email is fine, but anything in and out is getting 550 5.7.1 Unable to relay as an error. The virtual server is set to allow relay from all and anonymous access. Any suggestions appeciated.
