Fill in your account information as follows:
Your Name: This is your full first and last name.
E-mail Address: This is your full email address.
Incoming mail server (IMAP): mail.42inc.com
Outgoing mail server (SMTP): This is usually mail.42inc.com. However, if your ISP requires that you use their mail server to send mail, you will need to change this field to the SMTP server for your ISP. How do you know if you have to use your ISP's SMTP server? If you try to send mail after following these instructions, and cannot, then this is one of the most likely reasons.
User Name: This is your full email address.

Click on the More Settings button.

In the General tab, you can name your mail account. This is helpful when you have multiple email accounts.

Check the box for My outgoing server (SMTP) requires authentication. You can leave the default setting to Use same settings as my incoming mail server.
Click on the Advanced tab.

Check both boxes for This server requires an encrypted connection (SSL) in the Incoming server and Outgoing server sections. The numbers in the boxes will automatically change to 993 and 25.
