Is anyone having problems with sending emails

[ClaireH-184886]

I have been having problems for a number of weeks now, where if i send a couple of emails out then all of a sudden i am blocked and have to ask my hosting company for a new ip address.

my site is in joomla and my email address is through my site.

the messages i am getting when sending emails is as follows, and this stays like this until i get a new ip address

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:

This looks to be an IP problem obviously. But this could also be a faulty configuration in your DNS settings. I believe there is an setting for DNS managers where you set the name of the MAIL IP or URL.

I suggest contacting the host about the DNS settings or if you're using a type of DNS manager. I've seen this in CloudFlare where you have to set your configurations correctly prior to sending emails.
