Below you will find a list of the SMTP
server addresses for some popular ISPs. Your ISP will usually
require you to use their outgoing SMTP mail servers. You may also be
able to use your virtual domain server names through your hosted
Website/Email account, which would typically look like:
mail.yourdomain.com, however this method will require setting up
Outgoing Server Authentication for the POP3 account you will be
using.
