Hi,
One of our users recently received this message in reply to one of his outgoing emails.
"There was a SMTP communication problem with the recipient's email server. Please contact your system administrator. <domain.com #5.5.0 smtp;550 Sorry, we do not accept mail from hosts with dynamic IP or generic DNS PTR-records. Please get a custom reverse DNS name from your ISP for your host ip address or contact abuse@corp.mail.ru in case of error>"
We are running MS Exchange 2003, with a static IP from BT Business Broadband.
This is the first time we have encountered this problem.
Can anyone help me with a solution?
Any help appreciated, thanks.
