Hello
Although I have very limited IT knowledge, I am trying to set up a mailing group for coordinating sporting activities.
I managed to set one up on a WP Mailster plugin, but find that Google will block (most) messages to gmail addresses. I get a Remote server replied: 550 5.7.1 DMARC initiative. n1si38007006wrm.139 - gsmtp error message
So I moved to Groups.IO, much nicer as a mail group. This works instantly with gmail, but sadly seems to result in all messages to BT addresses being blocked. There is no error message, the emails just disappear into the ether.
In need a system that will succeed in delivering emails to people with a wide variety of email addresses. Is there some sort of special setting that would achieve that?
Any ideas? Is this a common experience, or should I be asking my ISP about it?
Thanks in advance
John Clube
