What are my SMTP settings?
Your smtp settings are...
Incoming - mail.yourdomainname.com
Outgoing - mail.yourdomainname.com
Some ISP's do not allow you to use your own outgoing SMTP settings
If you are using wannado/Freeserve as an ISP in which case the outgoing should be smtp.wannado.co.uk
If you can receive email ok but not send please submit a support ticket and we will try and resolve the situation for you. Please indicate your ISP when submitting the ticket.
