So I have the email address online...@telkomsa.net It's also setup as email@example.com. However when I send to firstname.lastname@example.org, it comes back with the message that email@example.com is not a known address on the server.
Yet under webmail.telkomsa.net, firstname.lastname@example.org is setup. Useless telkom email. And, no it is not my main email account. I give this email out as one which I don't care if it receives spam.
EDIT: What is strange is that when I send from this account, it shows is address as email@example.com
