eine frühere Nachricht von Ihnen erhalten habe:

Important warning!
The amount of unsolicited commercial junk mails ("SPAM") has increased dramatically. At the time of writing I receive typically 1500 spam mails per week, which is about ten times more than legitimate e-mail! About two thirds of these mails make it past the system-wide filters into my own filters, and these are documented in the graphs below. I have implemented e-mail filters to prevent myself from being flooded by spam. Therefore, do not send any message to me which is formatted in HTML! Moreover, MS-Word documents are not acceptable, because they may contain viruses. Use PDF instead! Only plain ASCII e-mails will be accepted by my mail system. No, I will not make an exception for anybody. (See below for more info.)
Furthermore, if you have never before sent e-mail to me or you have done so very rarely, include the following text on the "Subject:" -line. The text will act as an e-mail password and make sure that your e-mail reaches my mailbox. Note that the system is case sensitive! If you did send mail to me, but you are not sure whether or not your mail has actually reached me, resend it with the password on the "Subject:" -line.
Current e-mail password: asWQe10fv.
If, and only if you understand and agree to the above, you are
welcome to send e-mail to me to the following address:
SPAM protection enabled
My spam filters are based on "procmail" and "SpamAssassin." The
pages of Timo Salmi were of great help for establishing my filter system
(Thank you for the invaluable pages!). If you want to know more, the
following links are good starting points:
Why is HTML e-mail dangerous?
The most powerful mechanism for a spammer to verify the
validity of his e-mail list is by simply cross-referencing his web
server logs to the list. When the recipient HTML e-mail is opened, your
mail program sends requests (<a href=...>) to the spammer's
server in just the same way as if you'd accessed a regular web page. By
this mechanism, you explicitly tell the spammer that you received his
spam e-mail and that your e-mail address is in fact valid and in
use.
The crux is that in most e-mail programs, one needs to click on
a message first before one can mark it to be deleted (or move it into a
special "junk" folder). However, just clicking the message will display it
and thus send a message to the originator of the spam that your e-mail
address is valid and in use.
