greylisting added to (lists.)opensc.org smtp server [u]
I changed the configuration of the email server on (lists.)opensc.org
to use greylisting. So if you send a mail to opensc.org you might
experience a short delay of a few minutes, but no more. I expect
this technique to filter out a lot of spam (which I currently manualy
reject), but not cause any other trouble.
If you experience any problem, please let me know.
