I am having SBS 2003 Prem. and when I am sending mail to a selection of certain domains then an error from the local Exchange server gives the below:
There was a SMTP communication problem with the recipient's email server. Please contact your system administrator. <local.domain#5.5.0 smtp;550-Callout verification failed:>
