Plusnet email currently blacklisted by BT?

Boink · ‎23-02-2025

I tried sending test emails to various addresses and none are getting through to a btinternet.com address. This address receives other mail ok.

At first I thought it might be due to the client (Thunderbird), but the same happens when I send from plusnet webmail.

The emails properly go in the Sent folder, and I'm not getting a bounce or any other error message.

Blacklisted would have brought about an explicit NDR response. Are you sure that they have not gone to the spam folder?

@plusnettony is it possible that BT is grey listing *,plus.com?

Defiantly blacklisted.

I'm having problems too.

Cannot send emails on the PC connected to Plusnet nor can I send when connected to Vodafone mobile.

I still receive emails......

relay.plus.net isn't blacklisted....?

No!!!

A service being on a black list and a receiving serving blacklisting that service are not the same thing.

Where a service decides to refuse delivery permanently it should return a NDR. Where no NDR is returned there’s a fair possibility that the delivery is being deferred or grey listed. That’s exactly what Gmail does.

Ok.

So why can't I send emails?

Why the error? Nothing has changed in my settings.

I'm confused!!!!

How to I resolve this?

I had to set up a new IMAP account in TB to see the Spam folder, and yes, there they were! Thanks

@darrenbeddoes

That is a different matter (explicit blacklisting) discussed elsewhere around here.

@Townman
Thanks, I'll have a search when I get a little more time and see what I can do to resolve it.

I recently did a little research, as BT Internet's spam filter was hitting a small society mailing list I run (not via Plusnet).

Here are some instructions if you can persuade your correspondents to follow them:
https://www.bt.com/help/email/using-bt-mail-s-anti-spam-features (Scroll down to "Using the safe senders feature")

Or https://whitelist.guide/bt-email/ (Scroll down to "BT Mail safe senders list". This link also has some other useful suggestions.)
