If your Internet Service Provider's mail server is slow, or the provider does not offer an SMTP server, you can send e-mail through our mail (SMTP) server.
To do this, you need to log on to our SMTP server. You do not have to do this if you use your Internet Service Provider's server. This is so we can ensure that the mail server is not used for SPAM. To log on to Our SMTP server, you need to set up your mail client to use SMTP authentication.
To use Our SMTP server, enter customer-smtp.one.com and click "Next".
