Proprietary ISPs MSN Hotmail, MSN, AOL, and Yahoo! are supported via a special gateway called PopGate. Please use the following configuration on the POP Configuration page at https://webmail.spamcop.net/horde/imp/spamcop/popconfig.php or http://webmail.spamcop.net/horde/imp/spamcop/popconfig.php for each of them:
POP Server: popgate.cesmail.net
Username: Email Address at that ISP (including @hotmail.com, @msn.com, @aol.com, or @yahoo.com)
Password: Password for that Email Address
Please note that AOL Users incur minutes for the privilege of checking mail in this way. If you are not on an unlimited plan, beware!
Please also note that Yahoo! normally requires payment for the privilege of checking mail via POP, but this method is free.
