I'm not quite sure how I could explain it any better than I've already did in the different upstream bugs... =)
The problem is that with mboxo From_ lines (that is lines matching the regexp "^From (.*)$") in the mail header or body are converted to ">From \1". In simple words, the "From " is quoted with a ">". This is necessary, as From_ lines also serve as the separator lines for the different mails in a mbox(*) file. The problem with mboxo now is: From_ lines (in the mail body header) that are already preceded by one or more ">" are _not_ quoted. Therefore no MUA/tool can ever correctly unquote the content later when displaying it, because when it encounters a line like: >From Russia with love it can't know whether it read originally From Russia with love or whether it read originally already: >From Russia with love > Assuming the above, I am downgrading this to important, as it does not > seem to be a major use-case for evolution which warrants its exclusion > in wheezy. Well, for the reasons outline int the upstream bugs and before in the Debian bugs, I can't agree that this is justified. To be honest, trying to fight this bug at the different upstreams made me quite annoyed... and I've rather lost any interest helping other users not to suffer from it, too (which is why I brought up the suggestions what we can/should do IMHO at the Debian level to prevent our users from getting hit by it). Apparently many upstream developers/maintainers think as you, that it's fully ok to let users silently live with this allegedly "minor" corruption. Given that I think it's useless to repeat my arguments why it is not over and over again, I've forwarded[0] the question to d-d where the majority should perhaps decide how Debian should deal with such a corruption. Further I think it would be better for Debian as a "product" to handle this issue equally at all of it's affected packages. Feel free to add your arguments there :) > Or is evolution throwing away the whole mail or even mbox? No, but I don't think the severity is lowered therefore. Not only are users never informed that this happened for years with their mail... but also, whenever they work with mbox, e.g. importing their old archives,... all mails (with From_ lines) get corrupted... thereby braking signatures,... "binary" content like attached files with From_ lines or patches. [0] http://lists.debian.org/debian-devel/2012/11/msg00675.html
