outlook express outgoing mail issue in xp


  • Hi,

    In my company, we use windows mail who ever has OS vista and Outlook Express 6 who ever has OS xp pro. from couple of days we are facing problems of outgoing mails from outlook - Our webhosting server is in california and we are able to send/receive mail thru our webmail (squirrel mail).

    we are able to receive all mails but when sending mails the error is:
    An unknown error has occurred. Subject 'test mail', Account: '', Server: '', Protocol: SMTP, Port: 25, Secure(SSL): No, Error Number: 0x800CCC0B.

    When I tryrom run command telnet 25 I get 2 kind of replies
