Non-delivery of authentic emails

[David100]

I have just rechecked the Blocked List. The subject addresses are not on the list. Nor are the btinternet.com or gmail domains. I regularly receive emails from other people with both these domains.

Thank you for clearing that up.

Have you received a "new" email where they have entered your email address rather than using the "reply to" to funtion?

Have you added their email addresses to your "Safe Senders" list? It is found in the same place as the blocked senders list

Ref. Message 11 of 12, my reference to domains, there are examples of both domains attached to unknown addresses. I left them in place.

Ref. message 12 of 12; I have now added both email addresses relating to undelivered emails, to my list of safe senders, in settings. I will test these as soon as possible.

Well, one of my blocked addressees did respond and I received the message. However, on my Galaxy tablet the reply followed a warning which said that I had blocked the addressee and '.... that I will no longer receive messages from that address'. I will check again tomorrow.

The domains in your blocked list do not have addresses attached to them. 

If a domain is in your blocked list it will block every email address that comes from that domain. ie if gmail is blocked it will block every gmail email address that is trying to email you.

If gmail.com or BT.com or btinternet.com is there unblock them

[David100]

In my list of Blocked Senders there are no such domains, only email addresses. There are some gmail addressees which are still there, and was one btinternet.com addressee, which I deleted, rightly or wrongly.

Update: the second sender has responded which is interesting. This is the first message I have received from him, (though he claims he has sent me several, none of which I have received, not even in my spam folder). So I have had no opportunity to block him or his domain. Yet shown above the text of his message is a warning that his address has been blocked and no more messages will be allowed (or words to that effect). What is happening beyond my reach?

[David100]

Further to my last post, the warning message was only shown on messages received on my Samsung Galaxy Android tablet. This also applied to a third message, received today, this time from the service department of Sainsbury's, warning that this address had been blocked.  When I checked the list of blocked senders, Sainsbury's did not feature. So here is a another mysterious block being posted by a third party.

Although both computers, a tablet and a desktop PC, access the same BT account, do they each keep a list of blocked senders? I cannot think why that should be.

Notwithstanding this anomaly, I have not imposed any block on the quoted senders; so who has?

[gg30340]

BTMail uses the same blocked sender list on all your devices. It is held at a network level not on the device.

If the emails are getting through on some devices but not others then it is your device that is blocking them not BT.

For instance if you are using an email app on your Samsung rather than a web browser it may be that the app or your antivirus on the Samsung is blocking it and you will need to check there.

If Sainsbury is blocked how are you getting a message from the telling you it's blocked?

[David100]

Just to clarify, emails are being received on both devices, or not at all. At present the subject senders are succeeding.

The difference is that the tablet carries the warning that the sender is blocked, whereas the PC does not carry the warning.

Regarding Sainsbury, I receive many emails from them in conjunction with regular deliveries. Exceptionally, I received an email this morning from a different department advising a refund. That happens occasionally. But this morning I noticed the warning that Sainsbury was on my blocked list.

Has BT introduced a system which has unforeseen consequences? Otherwise, how can a first-time sender of emails (my second example) be blocked before I can take any action?
