I am the administrator of a domain (www.mydomain.com) that is hosted in a Spanish hosting. The fact is that one of the clients that uses the email [email protected] could not send an email from a city in Canada. Neither mail nor email did work through Outlook.
The client did not receive any error message, simply the emails were not sent or received.
Finally he had to use the web version of mail. The fact is that he asks me for a detailed answer. I, on the other hand, asked the technical service of the domain but his answer was:
It must be a network problem. We have no restrictions in any country
What explanation does this have?
