It is caused by an attempt to get a mailman URL that contains spaces or characters not in the printable ascii set [\x21-\x7e]. The reason behind this is to disallow CR and LF in particular. This was a security enhancement in Mailman 2.1.9. From the NEWS - A malicious user could visit a specially crafted URI and inject an apparent log message into Mailman's error log which might induce an unsuspecting administrator to visit a phishing site. This has been blocked. Thanks to Moritz Naumann for its discovery. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B. Dylan
