Afrihost just plain horrible, if you need help.....

I have spent R 200 airtime and waited the wole morning now to get Afrihost to fix one of their stufups. Completely oblivious. Bidorbuy is getting the following error when trying to send emails to my domain. Error 550, Sender has no A,AAAA or MX DNS record. Afrihost has no clue...... Good as ever Gian Visser !!!!, Keep it up !!!!
