As >far as I know, there's no single "best >practices" document to follow (and many "XYZ >considered harmful" ones and an interesting one about how Evolution works [1]). I read the following in RFC 5322: 'When the "Reply-To:" field is present, it indicates the address(es) to which the author of the message suggests that replies be sent.' You message did not contain a "Reply-To:" field. As such I am left will the following choices: (i) Reply to the author (ii) Reply to the mailing list (iii) Reply to the author and the mailing list I am replying to you and copying the message to the mailing list. It is a personal decision and not a "best practice". > Here's what I'd like to do: > >- Always offer multiple ways to reply.

Ok, you are using "List-Post:" to identify whether the reply to the list is possible. >2) "Reply All" option is always available and >will generate a list of recipients using the following rules: > > - All addresses in the message's From and > Reply-To will be used in the "To" field > - All addresses in the message's To will be in the Cc > - All addresses in the message's Cc will be in the Cc > - All addresses in the message's Bcc will be in the Bcc > >After this is complete, a list will be "sanitized": > - Duplicate enteries in each To/Cc/Bcc are be removed > - Addresses already in To are removed from Cc and Bcc > - Addresses already in Cc are removed from Bcc > >The List-Post and the Sender headers are ignored >when doing the Reply-All thing. The Bcc would be to your address. It's like replying to yourself. The "To" is similar if your address is in there. I could remove it or, if my MUA has the option, set a preference. If there is a "Reply-To:" I don't use the "From:". If the "Reply-To:" is set by the mailing list I could use the "From:" if I would like the reply to go to all addresses. >The "Reply All" is the second candidate for a >default (i.e. the default when "Reply List" is not available). > > >3) "Private Reply" option is always available >and produces a message with the following recipient(s) in the "To" field: > > - If the message contains a Reply-To, each of > those which are at the same time *not* listed > in any List-Post addresses are used.

Ok. There was a discussion about Bcc (see thread at http://www.ietf.org/mail-archive/web/ietf-smtp/current/msg00112.html ). There may be some good advice in there. Regards, -sm
