Can't send mail from iPhone

[Hoppy4]

Hi, regarding the above topic. 
do I need authorisation to send emails from a new iPhone, using their own email app. 
I don’t want to keep logging in to talk talk account, as no app available. 
I can receive email but not send. 
All configure settings are correct.

Hi @Hoppy4 

I've disentangled your post from the topic you posted on as that was about sending from overseas networks and I'll assume that's not your query?

What error message do you see when trying to send TalkTalk Mail from the iPhone?

You say the settings are correct so I'd like to see screenshots of the incoming and outgoing server settings please. Image edit to obscure the first part only of your TalkTalk Mail email address / Username before uploading the images here using the picture icon above this Reply area.

Please also confirm that your password is at least 8 characters formed of multicase letters, number(s) and at least one symbol.
