Hello,
We recently installed Exchange 2013 on a new Server with domain name ''sst.com.tn'' (it is the real domain name). Before purchasing the domain name we tested the internal mail and it works like a charm. However, when we purchased the domain name, we couldnt
sent internal mail BUT we can send external mail. I sent an email to my gmail account & it works, but when I replay from gmail (or any other mail) I get this delivery failure: "Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domainsst.com.tn by
redirect.ovh.net. [213.186.33.5] ".
any ideas please ?
