For some reason, one of the email accounts that I have set up in Plesk 7.5 Reloaded fails when trying to check pop3 mail. I have tried this in Outlook and Thunderbird. I get an authentication/login failure error. I tried the procedure via telnet and the login failed also: telnet mydomain.com 110 +OK Hello there. user lou +OK Password required. pass xxxxxxx -ERR Login failed. This problem only seems to happen with this one email account and only on occassion. This is a new Plesk 7.5 install on CentOS 3.4. Any ideas?
