SMTP authentication error

buchke — Fri, 03 Jul 2026 07:50:17 GMT

Hello,

In the last two days I can't send from my POP3 devices.

I can receive emails, the app works but my POP3 devices can't send.

If I try to re-apply my credentials it says my password is incorrect though I know it is correct.

My husband has exactly the same issue. It started to work again briefly yesterday but has failed again since last night.

Thanks

Ken

Problem solved - thanks to other people's posts.

I am visiting relatives and using their WiFi. If I go out into the garden (this is a remote area!) and pick up 4G, suspend WiFi then it all works perfectly.

On their WiFi everything works except sending mail from an android client on SMTP.

I've seen several other recent posts alluding to the idea that BT blacklists some WiFi. Anything I can do to try to unblock it?

Thanks

Ken
