Følgende e-mail adresser fejlede (The following address(es) failed):

  xxx@xxx.com
    SMTP error from remote mail server after RCPT TO:<xxx@xxx.com>:
    host mail.xxx.com [72.21.33.146]: 550-mx02.stofanet.dk [212.10.10.12] is currently not permitted to relay through
    550-this server. Perhaps you have not logged into the pop/imap server in the
    550-last 30 minutes or do not have SMTP Authentication turned on in your email
    550 client.

Jeg har sat SMTP Authentication on i Outlook express
