Communicator 4.x on Linux has been observed to insert + bogus unqualified Sender: headers -- i.e. Sender: headers with + only the username part of the email address. Other version of + Netscape may also have the same bug. + + By default, members-only lists use the From: header as the first + field to authenticate against, falling back to Sender:. The site + administrator can also configure Mailman to always use Sender: + first. If Sender: is used, and it exists in the email message, + but it is unqualified, it will never match a mailing list member's + address, and their post will always be held for approval. + + In the future, Mailman will improve its algorithm for finding a + matching address, but in the meantime, M. A. Lemburg <mal@lemburg.com> + provides the following advice. You can send this snippet to any user + whose posts are being held for seemingly no reason. + + Edit the two .js files in your .netscape directory (liprefs.js and + preferences.js) to include the function call: + + user_pref("mail.suppress_sender_header", true); + + BTW, the binary includes a comment which says that this is only + necessary on Unix. + + Since Communicator regenerates this file upon exit, the change + must be done when Communicator is not currently running. With the + next start, it will stop adding the Sender: header and things + start to work like a charm again. + + The reason things start to work again, is that Mailman falls back to + authenticating the From: header if the Sender: header is missing, + even if the site administrator has configured things to look at + Sender: first. + + +MOZILLA + + There are no known problems with Mozilla 0.9.x at this time.
