Hello, I would
like to have your help because since a time that my site does not send
the message of confirmation of registration and even all the messages. And at every 5 munite I receive the error messages " This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
ousma_n@yahoo.fr
host smtp.mailchannels.net [54.244.241.10]
SMTP error from remote mail server after end of data:
550 5.7.1 [ESA] Sender blocked. See https://console.mailchannels.net/insights/bounce?auid=arvixe&sender=noreply%40bresdel.com&txid=147dc9831ef319ec "
Thank you
