Since last friday (august 20th) we have problems with receiving mails. It started in the afternoon around 14:00h (CET). On saturday we received the delayed mail and it worked again. But since yesterday the forwarding stopped again.
On schuijffel.eu we seem to receive a part of the mails, on schuijffel.com I receive nothing. I added some other (extra) destination addresses, which do work. The problem I have is when mail is mapped to @ziggo.nl and @home.nl addresses.
Did you get any further with the problem? I informed my ISP, but haven't got any answer yet. Could you tell mee which server addresses (names) you use to deliver the mail to the ISP's? Maybe that will give them some clue.
