iphone won't send tiscali emails

First Timer
Message 3 of 3

My iphone receives emails OK but won't send them, I am using a tiscali email.


The error message is "cannot send mail. The sender address was invalid.

It says this for all new and even replies to emails, which clearly do have a valid email address.

Outgoing mail server I have set up as follows

Host Name:


Server Port 587


Any ideas or support would be welcome, thanks

Hi @Nicola28 


Usually this is because you're sending from an email address that isn't the tiscali email address. i.e. the default sender selected for your tiscali email account as added to your iPhone isn't the tiscali email address.


Take screenshots of the outgoing server settings and post here for review. Image edit to obscure the first part of your email address before uploading here using the camera or picture icon above this Reply area.


But just to cover the other situations that might arise, can you confirm you are a TalkTalk Consumer home broadband or Mail Plus mail only customer and that the tiscali mailbox address is added to your customer MyAccount, My Mailboxes? Managing your email in My Account
