    I did a search with Google....

    503 valid RCPT command must precede DATA
    If you get this error when sending email:

    The server responded: 503 valid RCPT command must precede DATA

    Try this solution:

    Means you must check your email before trying to send mail. The mail server requires authentication, which can be achieved using one of these methods:

    1. Pop before smtp -- check your email for new mail before trying to send email. This adds your IP address to a relayhosts file and allows any email to be sent from that IP address for up to 30 minutes. After 30 minutes you have to authenticate again.

    2. Configure your email client to authenticate automatically by checking the "my server requires authentication" box in your email configuration. You will be able to send mail without having to "pop" your mail box first.

    Hi hanspearce & welcome to Wilders, :D
    That message means that you first have to receive mail before sending mail.

    So POP before SMTP - this works for 15 minutes and then again receive, POP, and then sending, SMTP.

    I'm not sure if it has something to do with NOD32, so best let someone answer that who actually uses it.

    Hope that helps a bit. ;)

    Edit: :oops: ctrlaltdelete was quicker then me. ;)
