Hi there, I run my own mail server for my consulting company, hosted at Digital Ocean in New York. It has had the same IP address for a few years, I publish an SPF record, it has PTR records for both IPv6 and IPv4, and it does not send spam or act as an open relay or anything like that. However I still get the error 501 Connection rejected by policy [7.7] 9612 whenever I send to a company that uses Symantec Email Security (Messagelabs). Can you please delist my IP address, which is 192.241.243.54, and the domain is noware.co.uk.
thanks,
Neil Cook
