Emails to @btinternet.com addresses get NDR 554 bounces


[link to this post]
 
We are getting increasingly annoyed by group/bulk emails which we send out to the volunteers of our charity using Office 365 having ONLY those sent to @btinternet.com addresses being bounced with an NDR 554 Spam reason.

This is not consistent - emails to individual @btinternet.com addresses quite often get through.

I wonder whether anyone has done an Official Complaint to Gavin Patterson in the hope of getting this long-standing anomaly sorted out?

John,
This could be due to BTís anti spam mechanism, have you validated your outgoing email domain using a DKIM entry in your domain DNS settings?
https://docs.microsoft.com/en-us/office365/securityc...

Once validated it can take 24-48hrs for the amended DNS setting to filter across the internet.

Gavin Patterson isn't with BT Group any more.

My broadband basic info/help site - www.robertos.me.uk. Domains, site and mail hosting - Tsohost.
Connection - Three 4G, tbb tests normally 35-45Mpbs down, 65Mbps off-peak, 9-24 up.

BT's spam filter is catching identical bulk emails to multiple BT email addys.

BT's spam filter managed to filter off as spam an important email to me from BT itself so it seems BT thinks its own emails are spam!.
