Can anyone answer the below?
I’m trying to set up a website for someone and to send email from
talktalkbusiness.net. I was wondering if you could confirm the smtp
address and port number for talktalkbusiness.net. Also, do you know if
you can send emails from Outlook/Thunderbird as I keep getting a “relay
not permitted” error? Lastly, do you know anyone that has sent emails
from code what exactly they use in the “username” section? Is it the
part of the email before the “@” or the whole email address?
