SMTP stopped working after changing Broadband speed

[JohnMcDonald707]

It would be good to know if anybody in the Forum has a 900Mb BT Broadband service and uses STMP/POP/IMAP email.

I guess you didn't learn about flow control in your 40 years of networking.

I have no idea why you should make this comment about me . What is the basis for it? I tend to give my experience here to deter people thinking what I am saying has no value.  On the face of it, flow control would seem to be the problem in this case with the SMTP server/front end router. Is this what you are trying to say?

Hi Peter,

Did you highlight the problem to email team?

Thanks,

John

Hey again @JohnMcDonald707.

I last received an update this morning advising they'll raise it with the relevant team. 

If I get any further updates or need any specific details from yourself, I'll let you know!

Yes - I'm having real problems here with my new 900mbps service and sending (SMTP) bt emails - Did anybody see a way out of this.

Good morning @David_W102.

Just to double check, which client are you normally using to send, and do you get the same issues if you try BT Webmail?

Also is your 900 Mbps service on BT, EE, Plusnet, or another ISP?

Hi Peter...

So in answer to your questions:

Which client are you normally using to send: I normally use Thunderbird, But have also tried Outlook 2024. Both appear to be either not working or as I have noticed today , working but very slow to process a sent message.

Do you get the same issues if you try BT Webmail? : No - If I use a web based app I don't see a problem, messages get sent fine.

Also is your 900 Mbps service on BT, EE, Plusnet, or another ISP? I was using TalkTalk (FTTC) until recently. With them emails were sending fine. I have noticed the issue now I have moved to Full fibre with Toob.com. But this could just be a coincidence as overall I have found the Toob service to be working well re general web based working.

Thanks

David

I suspect Toob IP address pool is the problem here, there are other posts from Toob customers having mail problems.
