Email Server Settings FAQs (IMAP / SMTP)

Last Updated: Mon, 09 May 2016 > Related Articles


View common questions relating to email server settings.



What is IMAP and Secure IMAP?

IMAP stands for Internet Message Access Protocol. It is an Internet standard language used to receive email. Unlike the most common Internet standard for receiving mail, Post Office Protocol (POP), IMAP is designed to leave a copy of email messages on the server. This allows email messages to be viewed and managed on multiple devices (i.e. laptop, desktop, mobile phone, etc). Secure IMAP simply requires the use of a more secure connection between the device/software and the mail server to enhance security.

Does Secure IMAP allow customers to leave a copy of Contacts and Calendar on the server?

No. Secure IMAP is only for email messages.

What is the benefit of Secure IMAP?

Secure IMAP allows you to access email from whatever device you want and from remote locations.

What are the server and port settings for IMAP?

  • Incoming Mail Server: imap.coxmail.com, Port 993
  • Outgoing Mail Server: smtp.coxmail.com, Port 465

Do customers have to move to Secure IMAP?

No, customers can continue to use POP for receiving mail.

How do I configure IMAP settings for Cox Business Email on my mobile device (ex. Blackberry, IPhone, or Android based mobile phone)?

You can find the instructions on http://ww2.cox.com/business/support.cox to set up your mobile device to access Cox Business Email.

Note: Cox Business does not provide support for these devices. The IMAP settings information provided is for reference only. For additional information on setting up these devices, visit the manufacturer’s websites.


What is SMTP Authentication?

SMTP stands for Simple Mail Transfer Protocol. It is an Internet standard language used to send email. SMTP Authentication requires that a user provides a valid username and password to authenticate before the user is allowed to send email.

What is the benefit?

SMTP Authentication helps to minimize issues sending email using email clients (i.e. Microsoft Outlook) on networks other than Cox. For example, using your laptop in a coffee shop. It helps to ensure email sent from the Cox network is from legitimate customers and not spammers, therefore reducing SPAM.

Do I have to use SMTP Authentication to send Email?

It is recommended you use SMTP Authentication to send email for the reasons stated above.

What are the email client (ex. Microsoft Outlook) settings for SMTP Authentication?

Outgoing Mail Server: smtp.coxmail.com, Port 465
You must authenticate with your full user@domain.com and email password

What is Domain Name email?

Domain Name email allows you to access your email using a specific domain name (you@yourcompany.com) instead of using you@coxbusiness.com for example. This allows you to brand your email address with your business. With Cox Business Email, you can have at least 10 @coxbusiness.com mail boxes or 10 @yourcompany.com domain name email boxes at no extra charge.
