This article lists the email settings and port numbers for pop3 and imap configurations. It contains instructions for setting up Outlook 2003 as an email client for your POP3/IMAP mailbox.

Difference between POP3 and IMAP settings

Although POP3 is the preferred method, IMAP has its benefits. Imap offers a two-way communication between your Hosting Support mailbox and your email client(s). So, when you perform an action on your mailbox, or a message in your mailbox, it is immediately reflected on the email clients and mobile devices and vice versa (ex: if you log into your Hosting Support account, create a new folder, and put a message into that folder, this change will instantly and automatically appear in your email client, such as Outlook, and on your mobile device). Also, if you are at work, and you begin a message, and save it, it will still be there when you log in from a different client, say from home. 

IMAP provides a better method to access your mail from multiple devices, say from work, home, and your mobile, through two-way syncing capabilities between your mail clients and the Hosting Support mailbox. However, because IMAP saves all your messages on the server, be sure frequently clean up your mailbox, deleting old messages. 

Configure email server names and ports for POP3

The Email Server Names settings are:

  • Incoming Mail Server - (your domain suffix; com, net, info etc,)
  • Outgoing Mail Server -

The POP3 ports are: POP: 110 SMTP: 587

Configure email server names and ports for IMAP

  • Select IMAP as the setting in your email client
  • Incoming Mail Server - (your domain suffix; com, net, info etc,)
  • Outgoing Mail Server -

The IMAP ports are: IMAP: 143 SMTP: 587
