I don't know if that's relevent or not. One thing that comes to mind is that I know that some versions of Netscape for Unix had a bug which resulted in an invalid Sender: address being inserted into mail headers generated by the Netscape mail client. If your users are using Netscape for Unix and your mailing list is set to Send=Public that might have something to do with the problem, as LISTSERV will take the Sender: address to be the "real" address of the person sending the message and if that address is not subscribed will delay distribution of the message for ten minutes. (This is referred to as a "spam quarantine" and is to allow LISTSERV time to see if, for instance, the same email address sends the same message to a bunch of other mailing lists.) This wouldn't explain the four-day delays you mention, though, so even if this is part of the problem it probably isn't the whole story. I haven't used Netscape for Unix myself so the following information is culled from various sources, mainly mailing lists such as this one. I can't vouch for its total accuracy, therefore. To reiterate, affected versions of Netscape Messenger have the following bug: If the server login ID doesn't match the LHS of the e-mail address, Netscape Messenger generates a Sender line to try to authenticate who the "real sender" is. Unfortunately, this line is not correctly generated, resulting in a bad Sender line. A workaround is to set the mail.suppress_sender_header variable in Netscape's preferences file (unfortunately not accessible by the user interface). Close Netscape, open `~/.netscape/preferences.js' with a text editor, and add a line that says: user_pref("mail.suppress_sender_header", true); From then on, Netscape won't generate the "Sender:" header, and your message will be RFC822 compliant. I hope that you succeed in determining the cause of your problem. Thanks, -- Jacob Haller, Technical Support L-Soft international, Inc http://www.lsoft.com/
