In quantum physics, a quantum fluctuation is the temporary change in the amount of energy in a point in space, arising from Heisenberg's uncertainty principle. Quantum fluctuations are happening continuously. Most go unnoticed. However, according to modern theory, quantum fluctuations are the seed of the Big Bang which lead to our universe.

Think of this site in the same way. Most of the information here is just background noise on the Internet for most people. But there is a chance that the information here will change your life, or at least your day.

Is our mailserver rejecting your e-mail? 

Gloudemans.info, quantumfluctuations.nl and quantumfluctuations.eu use SPF (http://www.openspf.org), greylisting and various blacklists to validate mail sent to these domains.

• Normal mail servers handle mail as specified in the various standards defined for mailservers. Spammers are often not compliant with those standards. This is the basis for the Greylisting of mail. Each mail is identified by a unique triplet, sending mail server, sender and recipient. This first time a triplet is seen (in 30 days), mail is rejected with a try again later message. A mailserver properly implementing the mail standards will try again later. Many spammers never do. The second time a triplet is detected, mail is let through without any hindrance. The result is a substantial reduction in the volume of spam mails accepted by the mailserver.
