Ask us about your TalkTalk email account and Webmail.
yesterday
I have just added my Talktalk email account to a new MacBook. Since then, I have been unable to send Talktalk emails from my iPhone. Initially it said that I needed to enter my password for the Talktalk account. Now it says ‘Cannot send mail: The sender address was invalid’. The outgoing server settings are correct.
Many thanks for any help.
