this maybe a simple question. A company owns two domain names let say a.com & b.com, the a.com is the main exchange email address pointing at the server via MX records & b.com also has records pointing at the server. they are selling off company a.com but keeping the server running email for the b.com address. now i can re-point the mail to the new company's server for the a.com email & take off that email domain on the existing server, is there anything i need to watch for doing this as they want to keep the server to collect email for their second domain b.com?
I hope you understand this question.
