Hola,
estoy intentando enviar un email a una cuenta de ono.com pero me devuelve este email:
Cita: Hi. This is the qmail-send program at [IP].
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
<**********@ono.com>:
Sorry, I wasn't able to establish an SMTP connection. (#4.4.1) I'm not going to try again; this message has been in the queue too long.
--- Enclosed are the original headers of the message.
En teoría esa cuenta existe. Entonces porque devuelve eso?
saludos
