Signature Stripping and anon servers

Message-ID: <gkremenCtMrv2.190@netcom.com> Organization: NETCOM On-line Communication Services (408 261-4700 guest) Date: Thu, 28 Jul 1994 03:18:38 GMT Lines: 25 I am new to this group so please forgive my ignorance. I am looking at putting together a local anonymous server. However, people here have signatures that might give them away. They also forget that they have signatures. Is there a general (and I know that you can't cover all cases) of stripping signatures? What I was thinking about was: Read last 100 lines of message if a line begins with -- then if no MIME v1.0 header present then delete last 100 lines else if -- is part of part-boundary then ignore else delete last 100 lines Does anyone have any gross problems with this methodology? If so or if you have any suggestions, send mail to me and I will post the best stuff. Thanks in advance. Gary

Yes. I believe that your pseudocode is buggy. First, I believe that you should match the regular expression "^--[ \t]*$" rather than just ``line begins with --''. Secondly, you should have ``delete everything from the matching line to the end'' in place of ``delete last 100 lines''. For this message, your algorithm would delete the entire message. -- Rick Busdiecker <rfb@lehman.com> Please do not send electronic junk mail!
