Thank you for your feedback. I'm most inclined to handle replies based on the needs of the particular list. Personally I find myself sending most replies to the list address and for small lists like the ones I run, I think that's the best choice. So I'm inclined to add/replace the reply to header to the list address. I know many high traffic lists prefer the reply to default directly to the sender. In that case, if there is an existing reply-to, I would keep that, otherwise, copy the original from header into the reply-to. I run a mail client (thunderbird) which recognizes mailing lists, and so provides me with a reply and a reply-list button. My sense is that there are alot of mail clients that don't do that, so the default has to take that into consideration. I think the defaults should provide the best support for non-technical/inexperienced users. Yahoo, by default adds a reply-to header. > > RFC nitpick: the mailbox part of an address is limited to 64 > characters, so this has some risk of violating that limit, and there > are a few MTAs that care.

Ok, I will consider that, though if I really get mailbox names that long, maybe they should be treated as spam anyway. > > R's, > John ------------------------------------------------------ Mailman-Users mailing list Mailman-Users@python.org https://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: https://mail.python.org/mailman/options/mailman-users/archive%40jab.org
