I use Forte Agent to send email, via Virgin's mail servers, with
replies forwarded via my own domain email address.

I have set up the Gmail app password, which has been working
fine, but am now getting bounce messages like this:

>Action: failed
>Final-Recipient: xxxxxxxxxxxxxxxx
>Status: 5.0.0
>Remote-MTA: dns; gmail-smtp-in.l.google.com
>Diagnostic-Code: smtp; 550-5.7.26 Your email has been blocked because the sender is unauthenticated.

The IP address varies in different messages, all allocated by
Virgin's mail server, and clearly not unique to me.

I have read the various pages of instructions, including one on
my host:
<https://www.heartinternet.uk/support/article/how-do-i-add-spf-records-to-my-site.html>

but find myself totally unable to understand exactly what to do.
It also seems like trial and error is not a good way to go, if I
correctly understand that updated entries can take up to 48 hours
to propagate.

If I send directly from Virgin's online mail page, there are no
issues.
