The error:
"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."


it means that an email has been sent to our SMTP server.
Our SMTP server looked for the recipient's SMTP server but was unable to establish the connection after several attempts.
It is often because the destination server does not work or is temporarily inactive.

The problem must be solved by the recipient, notifying your hosting provider.
