Description Luke-Jr 2005-02-22 12:34:23 UTC

Version:            (using KDE Devel)
Installed from:    Compiled sources

RFC 2369 states:
"A list of multiple, alternate, URLs MAY be specified by a comma-separated list of angle-bracket enclosed URLs. The URLs have order of preference from left to right. The client application should use the left most protocol that it supports, or knows how to access by a separate application. By this mechanism, protocols like http may be specified while still providing the basic mailto support for those clients who do not have access to non-mail protocols. The client should only use one of the available URLs for a command, using another only if the first one used failed."

KMail handles this properly when populating the folder mailing list information, but attempting to "Reply to All" does not filter duplicate posting addresses: If the message is "To" x@lists.y.net and the "List-Post" is x@y.net, x@lists.y.net, and x@ml.y.net, KMail will address a Reply to All to x@y.net *and* x@lists.y.net

Test case headers:
List-Post: <mailto:gentoo-amd64@gentoo.org>, <mailto:gentoo-amd64@robin.gentoo.org>, <mailto:gentoo-amd64@lists.gentoo.org>
To: gentoo-amd64@robin.gentoo.org

do you still have the problem with recent version?

Comment 2 Martin Koller 2009-09-29 21:59:07 UTC

I can reproduce this with KDE 4.3.1, however I do not see this as a bug.
RFC2369 does not describe what to do on Reply-All.
In my test, kmail creates a mail with
To: gentoo-amd64@gentoo.org  (this is the first List-Post address)
CC: the From address
CC: gentoo-amd64@robin.gentoo.org  (the original To: address)
