Actually, these are MIME headers, not body lines and Mailman does fold long headers in accord with RFC2822 sec 2.2.3 The problem is that this folding is only supposed to be done where the standard allows for "folding white space" which is where the type or amount of white space is not syntactically significant. Here the folding is done inside of a quoted string which represents a file name and that appears to be wrong. I have tested this with my own installation sending one message to me directly, to me via Mailman listname-owner, to me via a Mailman list and to me via the MTAs on the Mailman machine and procmail. The two messages that went through Mailman got the file name folded and the other two didn't. Headers as sent and received not through mailman were >Content-Type: message/rfc822; > name="Make the name a whole bunch longerRe [Mailman-Users] Admin unsubscribe > members by e-mail.eml" >Content-Transfer-Encoding: base64 >Content-Disposition: attachment; > filename="Make the name a whole bunch longerRe [Mailman-Users] Admin > unsubscribe members by e-mail.eml" Headers that passed through mailman were >Content-Type: message/rfc822; > name="Make the name a whole bunch longerRe [Mailman-Users] Admin > unsubscribe members by e-mail.eml" >Content-Transfer-Encoding: base64 >Content-Disposition: attachment; > filename="Make the name a whole bunch longerRe [Mailman-Users] Admin > unsubscribe members by e-mail.eml" -- Mark Sapiro <[EMAIL PROTECTED]> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
