Hello, as the title says does not come to my e-mail messages sent by others on any email box.
But can send
From what can be?
Howdy,
Well, it can be a lot of things 
When attempting to send an email to someone on your server, do you receive an error message in your email client?
What about in the mail logs, either /var/log/maillog or /var/log/mail.log – are there any messages that show up in there?
