Can not check MX records for recipient host company1.com Does it mean that the domain "company1.com" does not have a mail server associated with it? If so, how do I check if there exists an MX record for a particular domain. I used to ping to mail. and see if it resolves. That apparently is not the right approach as the emails sent to a user today, generated the above error even though I'm able to ping mail. for his email address. Thanks for your time.
