Ik krijg regelmatig, meestal aan het eind van de middag een grote hoeveelheid "Undelivered Mail Returned to Sender" mails in mailbox. Waarschijnlijk misbruikt iemand mijn account om mails te versturen die vervolgens afketsen op een server.
Inhoud van de mail ziet er meestal vergelijkbaar uit als deze:
This is the mail system at host smtp03.glasoperator.nl. I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below. For further assistance, please send mail to postmaster.If you do so, please include this problem report. You candelete your own text from the attached returned message.
