[dalecollins]

I have my own server in my home for my bowls club yelvertonbowling.co.uk and when i try to send or receive  emails I get the message below. How can I sort this?

This is the mail system at host host.yelvertonbowling1.co.uk.

I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can
delete your own text from the attached returned message.

This is just a customer to customer help forum, everyone here, including myself, are just customers.

The only BT Employees are the forum moderators.

Please edit out any email addresses, as they are not permitted on this public forum.

You will also attract a lot of spam.

I advise not running a mail server on a dynamic IP address and on a residential broadband connection as it as you have seen will be blocked by email servers.

If you must run your own email server you need to move to a proper cloud provider or a virtual server in a data center with a static IP address.

See my other response to someone else who tried this and got the same: https://community.bt.com/t5/Email/Policy-Blocklist-PBL/m-p/2225684/highlight/true#M100581

All residential based dynamic IP address are on a Blocklist from sending unauthenticated emails.
