Trying to switch one of my clients from POP to IMAP resulted in error... Apparently COX supports IMAP for business accounts only... Residential customers left with POP support!
pop.coxmail.com / port 995 / SSL
imap.coxmail.com / port 993 / SSL
smtp.coxmail.com / port 465 / SSL
(if you can not find dedicated entries for your server ports, or on the mobile device use server:port format on the server entry)
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 a viewed and
managed by multiple devices (i.e. laptop, desktop, mobile phone, etc),
hence providing email mobility. Secure IMAP simply requires the use of a
more secure connection between the device/software and the mail server
to enhance security.
