EE broadband and SMTP settings post move from BT broadband

[SimonJX]

I have just moved from BT Broadband to EE broadband.

I was told I would keep my BT email addresses and nothing would change.

I have an email client on my laptop (Thunderbird) and one on my android phone (BlueMail).

I can log all my email accounts on to the BT Webmail so two things, they are working and the passwords are correct.

I can pull the emails to my phone and laptop so the IMAP is working correctly.

I can send emails from the webmail client fine.

I cannot send from my phone or laptop. I get an error:

Sending of the message failed.
Unable to authenticate to Outgoing server (SMTP) mail.btinternet.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'.

Been there done that, nothing has changed except going from BT to EE.

I have spoken to EE / BT faults and they say my email accounts are fine and the problem must be with my email clients and they didn't know what a SMTP server was.

I guess the first question is does SMTP exist with EE broadband ?

Second question has anyone else been there and done this and used SMTP ?

Thirdly if you did move from BT to EE and had problems sending via an email client how did you fix it ?

I suspect BT haven't set my email account correctly but who knows.

If I can't resolve this I think I'll exercise my 14 days and just go back to BT as I use SMTP for my email devices and have no interest in webmail as a work around.

@SimonJX : SMTP & email in general have nowt to do with EE but with your email provider.

Almost certainly you are using the BT unauthenticated SMTP on port 25. BT will only allow that when you are coming in from BT's own BB network, not somebody else's. You need to change it to authenticated SMTP on port 465 with SSL encryption & authenticated by your BT Mail Username & pwd. 

Whoever you spoke to in BT should have well known this off their bat. It's all in their own publication BT Email server settings
