Can anyone offer any assistance into why I am getting this error. vchkpw: vchkpw: Read error This is a clean install of vpopmail-4.9.9, using mysql for authentication. I can add/delete domains fine, no errors, but when trying to authenticate, i get "authorization failed", see my telnet session below Trying 192.168.34.10... Connected to xenon.i9000networks.com. Escape character is '^]'. +OK <17152.986293680@xenon> user [EMAIL PROTECTED] +OK pass test -ERR authorization failed Connection closed by foreign host. I also get this in my sylog.
