A note on this subject, of a problem that I am having.
I have 8 equestrian?groups here in New Zealand, that I am the only moderator of. Our Telco?ISP is called xtra, which is my ISP.?I have put my own email address in each group so I know that any email I send to groups.io is sent out. All was working well, then I noticed? I was only getting returns from some groups, very intermittent! Then I got an email from groups.io to unbounce my account. I did this and started doing some investigations, and found that of the approx. 1600 addresses in my groups,?over 400 of the "xtra"?address had the red "B" (Bounced)?against them. Addresses with other ISP's are working fine.
I have tried sending some of them a bounce probe, doesn't work as xtra has blocked anything from groups.io! Unless they have unbounced their account.
Now trying to get xtra to lift the block on groups.io, then I will need to send an email to all the xtra addresses directly to not treat the "unbounce" link as a spam or phishing email, as I thought it was when I first saw it.
The cause that started it: I use Thunderbird for my emails. If I put an attachment into the box at the top with the lines in it, and send it to groups.io to be sent out, xtra would bounce them! If I put the attachment into the body of the email, it works fine. Very odd.
Hope I get some sense from xtra soon.

Barry.
