It sounds like a few things changed at/around the same time, so I would try
to reduce these to find the root cause of the issue.
First, can your system send an email successfully to the name at gmail.com but
with a pdf attachment ?
Can you include another email address (say your address) as a BCC to the
email being sent to name at gmail.com ?
You will them be able to view the raw message including all headers in your
copy of the message.
One of my systems send emails with pdf attachments and it will send to gmail
addresses without issue. The messages are being sent from an Microsoft365
mailbox using the latest Studio 10.2, I do not set a messageID header
manually, Office365 takes care of that for me.

Internet provider is Telstra : smtp.telstra.com works for all
The business just recently changed their email address to a business email
with a new company. I was wondering whether this may be a problem and they
may require some other authorisation.
What settings do you require to allow emails to go by smtp too gmail
Any ideas would be greatly appreciated
