TELKOM AUTO REPLY OUT OF OFFICE DOES NOT WORK

Telkom auto reply only works for Telkom email addresses not any others eg a “g mail” email address and so on. The Telkom auto reply /out of office facility used to work as an auto reply should for any emails sent. It no longer works. Telkom cannot get its out of office/auto reply to work unless the email address is a telkomsa.net email address. I have communicated in every possible way with them over the course of about a month and a half. I have had 2 IT consultants – 1 my own local and a 2nd renowned international IT consultant fully look into the problem. Both independently agree that the problem is on Telkom’s side. I have kept correspondence exceptionally simple for Telkom. Have told them in point form –1. I have set the auto reply and it has remained set for them to test 2. The auto reply only works for Telkom email addresses , not others and given the different email addresses that it does not work for. Their response to this was mere complete incompetence. Pathetic idiotic responses such as “ you need to set the auto reply from your side”! …I have just told them in every single correspondence that this is what I have done. Anyway, the some total of their response to me after I told them I have the auto reply set, was to inform me that I need to set it! I have a professional practice, where it is of vital importance that an auto reply is sent. I first set it on 4th of May 2018 and to date it still does not work, nor have I had any level of vaguely intelligent response from Telkom.
