Incoming Emails from a trusted source are bouncing...

[MalcolmRogers]

Hi - I run a local Scout Group - last week all emails from our contact system to members with btinternet.com email addresses started bouncing and being undelivered (including to myself).  It seems to be a national problem as Scouts across the UK are reporting the same error!!!

How do we get this addressed urgently please.

Hi @MalcolmRogers 

Have a look at the postmasters best practices: https://www.bt.com/help/email/fix-a-problem/sending-or-receiving-email/bt-email---best-practices-for...

Make sure your email domain has SPF, DKIM and DMARC policies and your email reputation is good.

Also make sure your sending mail server IP address are not on any blocked list or have a bad reputation too.

For mailing lists and sending emails to multiple users make sure you're following the best practices - use a mailing system designed for that (don't just BCC email address)

Hi Jac -thanks for responding.  I've passed those suggestions to the company who operate our management system - it's a bit over my head!

The issue is clearly not as mentioned, if that was the case - then it would affect countless others who use different mail providers, but it does NOT.

The problem is, and always has been, BTinternet email and the way it is run. It is patently not best practice, and BT will not do anything about this.
