I am having trouble replying to an E-mail.
I have previously replied to this e-mail (about 10 days ago) without any issue.
But now when i try to reply i get Delivery has failed message Your message wasn't delivered because the recipient's email provider rejected it.
I have tried sending this through Microsoft Exchange, BT POP3 Account and G-mail and they all fail.
The error messages i get are as follows:-
#< #5.4.4 X-Postfix-smtp: Host or domain name not found. Name service error for name=mxmail.gov.mu type=A: Host not found> #SMTP#
Remote Server returned '5220.127.116.11 Proxy session setup failed on Frontend with '554 5.4.4 SMTPSEND.DNS.NonExistentDomain; nonexistent domain"
