upon opening O E and connecting I get the following message:

The host 'mail.ev1.net' could not be found. Please verify that you have
entered the server name correctly. Account: 'nancc', Server: 'mail.ev1.net',
Protocol: POP3, Port: 110, Secure(SSL): No, Socket Error: 11001, Error
Number: 0x800CCC0D

then it seems that my messages are downloaded
what is this error message trying to tell me and what should I do about it
what do I do to clear it?
