I also own and moderate a group with a few btinternet.com e-mail
addresses in it. I have three of my own e-mail addresses registered
to get a good view of the workings of the group, one of them a
btinternet.com one, and have not seen any problems. Outside
groups.io, I did have a problem where messages sent to my
btinternet.com address about local refuse collection problems were
being bounced by BT (i.e, complete rejection rather than delivery to
Spam) because the subject line had both of the words "tax" and
"refund" in them.
The postmaster team at BT explained "the rejection is to protect our
users from scam emails promising Tax Refunds, only Government
domains are allowed this subject as they are the only ones who issue
Tax Refunds. HMRC were the 3rd most scammed brand worldwide hence
the block.
It is just the Subject line which is affected, those with both TAX
and REFUND."
Perhaps not the problem underlying this thread, but worth bearing in
mind - subject wording can have this effect.

Tim Mitchell.

Hi John,
I am the owner and moderator of a group which is based on studying
the history of a specific railway geographically based in the UK.
Many of the members are also based in the UK. I just scanned
through the member list and found that 217 out of 1505 have to
various BT email addresses (BTInternet, BTConnect or BTOpenworld).
We migrated to Groups.io last February and have sent out around
8,000 messages since then. I have not ever heard of any specifc
problem affecting these BT addresses. So I would challenge your
assumption that there is a general problem between BT addresses
and Groups.io.
You might want to add another BT email address from someone you
know and have them run some tests and see if they have the same
problem. Then you can narrow it down to something in your setup
specifically.
Before you test with another member, it would be worth checking if
BT are sending any error messages back to Groups.io. All reputable
email services provide this kind of feedback, but I wonder if BT
fall into this category <smile>. Just click on
"Subscription" in the left hand column, on the web version of
Groups.io, and then click on the "Email Delivery History" tab.
Tell use what you see there. You can try this both when you have
the GroupManagersForum group open and when in your test group.
This link will take you straight to the Email Delivery History in
the GroupManagerForum :-
/g/GroupManagersForum/subdeliveries
If there are any messages coming back from BT email about the
errors, then they will be listed there under "Most Recent
Unsuccessful Attempt" or "Recent Bounces".
