As a requirement of the subscription with the University Of Berlin, I am required to publish a valid email address with all posts, and this I do.
However, all unsolicited emails to that address are unconditionally deleted without being read.
Only emails bearing the pre-agreed security code in the title are downloaded from lycos. All the rest are deleted at the server.
(So whoever is sending me regular emails every half hour or so with malicious attachments of either 153kB or 141 kB is wasting their time. Mr.Stephenson's email with a 5MB attachment (malicious, or what!?) which has been sent twice was binned in both cases)
