* providers/pop3/camel-pop3-store.c (camel_pop3_command): Fix a bug in error-setting code. (pop3_connect): Don't re-prompt for password in the KPOP case. (pop3_get_response): New function, split out from camel_pop3_command. (connect_to_server): Use pop3_get_response to parse the greeting message, and error out appropriately if it's -ERR. svn path=/trunk/; revision=3869
