    Getting error 554 while sending newsletters via Outlook Express on Windows XP

    Yesterday, I try to send a large number of sending newsletters through Outlook Express on my PC running on Windows XP and the process get completed about 80%. After that, I got an unknown error with the information saying “Account: ‘mail.comcast.net’, Server: ‘smtp.comcast.net’, Protocol: SMTP, Server Response: ‘554 omta12.emeryville.ca.mail.comcast.net comcast Message sending error”. In what way can I fix up this error?

    Dear friend,

    You have received this message because your email server, from which you are sending bulk newsletters, is not able to identify itself when it is connecting to comcast.net servers.
    May you have been blocked from emailing the comcast.net.
    The reason is that when you try to send a large number of newsletters through Outlook express, you are assumed as spammer by the comcast.net network.
    To solve this problem, try to send newsletters in small bunches or you should contact your email administrator with your problem.

    Thanks!

    it is an
    Authentication Credentials Error

    554 Originator address does not match authentication credentials.
    it happen because the SMTP sender email address does not match with the address in exchange dirrectory

    click Properties
    and then click the General tab
    add address too exchange directory it may solve your problem
