If they have decided to enforce AUTH for all relayed mail, it will be a challenge if you do not have the AUTH details. They probably published the information somewhere or they don't want any TDH relaying through their servers. Use your own SMTP Server sir.

@Wash , the shocker is that this is when a client sends emails to me , i can send to outside domains very nicely , basically they've blocked their own MX servers from relaying mails to my server , and they're are the ones hosting all services in my domain.

So they need to configure it with AUTH params. Maybe it's new students playing with server configs! On 27 November 2017 at 16:50, geoffrey gitagia <ggitagia@gmail.com> wrote:

Alex, AUTHentication requires that you also have a username+password pair. What if you don't? Plus GG is saying that it's mail being sent to him, not by him. It's a little confusing reading what he's saying. On 27 November 2017 at 16:49, Alex Watila via skunkworks < skunkworks@lists.my.co.ke> wrote:
