To send email messages you need use SMTP server (SMTP - Simple Mail Transport Protocol). When you setting up your email client you must fill two important fields. These are POP3 or IMAP server (for receiving mail on your box) and SMTP server (for sending mail).

1. You can use SMTP of your local Internet Service Provider (ISP). This is the most common way. You receive SMTP server access info with your internet access account info from your ISP.
We always recommend you to use this SMTP.

2. If you are our client and "simpledomain.com" is your domain hosted with us you can use our SMTP server. To use it you need put in the SMTP server field of your mail client "simpledomain.com" (i.e. your domain name without 'www'). Then you need set up SMTP authorization ('My server requires authorization' in the MS Outlook mail account settings). Login and password for SMTP authentication are the same as your mailbox ones.
