I can send email between mail accounts within my domain fine, but when I send email from say gmail account to a domain email it is not received or bounced back on gmail end? any ideas?
Thank you for you post. Quick question, does this also occur with other 3rd party email addresses like yahoo or hotmail. If so, this may be a sign that there is a conflict with the Mail Exchanger records (MX records) within the domains DNS. I recommend bringing this to the attention of or 24/7 support team so that they may review the settings to see if there are any conflicts. Thank you.
I'm having the same issue. I can send from firstname.lastname@example.org to email@example.com but no external emails are being received and my mail clients as well as my iPhone can't connect to the server.
