Exchange 2003 : Default Blocking Message
Hi All, One of our customers is getting a error message when trying to send email to a specified recipient. Here's the error message : There was a SMTP communication problem with the recipient's email server. Please contact your system administrator. <servername.domain.com #5.5.0 smtp;552 Default Blocking Message> I guess the problem is with the recipient's email server, but I'd like to know the reason? Any Q? Thanks!

Hi John, This might caused by one of the following. Mail box size limit exceeded the default Mail Size Exceeded the default Some of your global transport limits are exceeded. Try to check those .. you may be able to fix it.

With such a non-descriptive error text to work with you'd have to contact the admin of the other domain and ask them what they meant. It looks to me as if they have some anti-spam software (or an appliance) for which they haven't provided their own descriptive text. 552 is just a generic status code. RFC2821 defines that code as: 552 Requested mail action aborted: exceeded storage allocation But who knows what the other machine *really* means?! --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
