When setting up my mail client (Outlook 2013), all steps are followed as per the guide.
Test mails are received and visibile in the mailbox. Its external email which are not received (have checked junk folder as well) as a result, an error message is delivered ie delayed or delivery failure. Current set up:
POP - mail.domainname.co.za
SMTP - same as OPO
What could be wrong and how can I resolve?
