One of the subscribers to this Forum alerted me today about an e-mail he received, using his Forum screen name and e-mail address, regarding the change of his password that he did not request himself.

DO IGNORE THAT E-MAIL. IT WAS NOT SENT BY ME.

Will look into the cause of this and see whether it's a security breach of the forum. If others also received such an e-mail, please report in this topic.

To the person that sent me this alert this morning: my regular e-mails to you now also bounce with a Delivery Status Notification (Failure).
They did so already the day before yesterday, it went well this morning for a short period, but I now get them back undelivered.
