  1. Dear Friends,

    I use outlook express for accessing my rediffmailpro account, some how when i try to sent a message, it shows the following error:

    The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was Subject 'Re: Account: ' Server: '', Protocol: SMTP, Server Response: '553 sorry, Authentication failed or timed out. Please do get messages first to authenticate yourself.(#4.4.3)', Port: 25, Secure(SSL): No, Server Error: 553, Error Number: 0x800CCC79

    after some trials of automatic send-recieve the message gets sent, wonder if i have to send an urgent message how do i do that.

    can anyone help.
