Hi, Let me quote from the Gnus manual, which explains how some think it should be handled.
Sometimes while posting to mailing lists, the poster needs to direct followups to the post to specific places. The Mail-Followup-To (MFT) was created to enable just this. Three example scenarios where this is useful: * A mailing list poster can use MFT to express that responses should be sent to just the list, and not the poster as well. This will happen if the poster is already subscribed to the list. * A mailing list poster can use MFT to express that responses should be sent to the list and the poster as well. This will happen if the poster is not subscribed to the list. * If a message is posted to several mailing lists, MFT may also be used to direct the following discussion to one list only, because discussions that are spread over several lists tend to be fragmented and very difficult to follow. Gnus honors the MFT header in other's messages (i.e. while following up to someone else's post) and also provides support for generating sensible MFT headers for outgoing messages as well. The basic rule is that the first poster to a thread decides what to do, any later reply may change that - but only by adding CC headers. Without that rule some may miss a mail. Gnus considers a missed mail more serious than a duplicated mail. If you delay mail receiving for a a few minutes, it is possible to use the message-id to filter out the duplicates. Well, this does not work always (e.g. due to greylisting) but it has the ability to remove duplicates in many cases. For many years I used Gnus internal mail splitting which handles duplicates suppression very well. Meanwhile I switched back to procmail and a local imapd. This does not have the the full Gnus filtering and I also did not implemented the above strategy. It doesn't harm - I check my general folder for important messages and then turn to the mailing lists. By reading the mailing lists the duplicates in the general mail folder will also be marked. Salam-Shalom, Werner ps. Things which annoy me much more than CCs are: top posting, not stripping long quotes, missing to insert a "was:" after changing the subject, and changing the name part of the address to include the list name. -- Die Gedanken sind frei.
