Apparently, Microsoft Exchange mails a calendar with a text/plain alternative for those mail clients that don't understand the calendar in the same way as it might include a text/plain alternative to a text/html message. Since your content filtering options include "collapse_alternatives = yes", Mailman selects only the first alternative of those that remain after initial filtering for delivery to the list. Thus the text/calendar alternative is dropped in favor of the text/plain alternative. You have two choices: 1) teach Microsoft Exchange to send the calendar part only without the text/plain alternative, or generate the message differently so it does that, or 2) set "collapse_alternatives = no", but this may have other, unwanted effects. -- Mark Sapiro <[EMAIL PROTECTED]> The highway is for gamblers, San Francisco Bay Area, Californiabetter use your sense - B.

[Mailman-Users] ics / iCalendar attachments?
Has anyone configured Mailman to allow ICS / iCalendar attachments? I've added text/calendar to the pass_mime_types setting in content filtering, but the ICS attachment was removed. The full content of pass_mime_types is: multipart/mixed multipart/alternative multipart/related text/plain text/html text/calendar application/pdf Here's how the mime attachment was included for the ICS file (I mangled it a bit to make sure it didn't get parsed) ... -- Content- Type: text/calendar; method=REQUEST; name=invite.ics; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Content-Disposition: inline BEGIN:VCALENDAR PRODID:-//Google Inc//Google Calendar 70.9054//EN VERSION:2.0 CALSCALE:GREGORIAN METHOD:REQUEST -- Any suggestions?
