Hello, Good morning..
My problem is the following..
I have an account with 11 active corporate emails. But, for 2 days, I had a problem with the reception from other domains mail.
I can not receive any mail, I get this error: " Mail delivery subsystem "
I have my domain configured correctly, I check the page and all data from dns, mx, cname are correct.
The strange thing is that we have been with this service for almost a year and it worked correctly, the problem has been presented for 2 days
have my domain in http://eros.venezuela.dns, the domain payment is up to date, I would like to know what is happening, it is urgent, since we work through emails and we need active service
