Auto forward rule randomly fails

Modenese — Tue, 28 Mar 2023 20:51:00 GMT

I'm a BT Fibre 2 customer.
I have a BT Standard email account (x.y@btinternet.com) that is assigned to 'friends and family'.
I've set up a rule for this email account using the BTemail web client to auto-forward all its incoming emails to a.b@gmail.com , and keep a copy of the mails in x.y@btinternet.com
This works ... most of the time.
But occasionally the original sender of the email gets an undeliverable message along the lines of

From: Email Administrator <postmaster@btinternet.com>

To: sender @ outlook.com
Subject: Undeliverable: A test message to your BT internet address

Sorry, your message cannot be delivered. The mailbox you are trying to send to is currently unavailable or disabled, or your email has been rejected for policy reasons

Your message was rejected by gmail-smtp-in.l.google.com for the following reason:

5.7.25 [213.120.69.23] The IP address sending this message does not have a
5.7.25 PTR record setup, or the corresponding forward DNS entry does not
5.7.25 point to the sending IP. As a policy, Gmail does not accept messages

The following recipients did not receive this message:

<a.b @ gmail.com>

So although I do get a copy of the message delivered to my x.y @btinternet.com mailbox, the original sender sees a 'your-message-has-bounced' headline and thinks that the message is undeliverable. And my gmail.com account doesn't receive a forwarded copy of the message.

QUESTION: Is there anything that an end user of BTemail can do to fix this issue?
