But apart from this,... yes you're right, Wietse already said he would probably accept such a patch, but with the default still exposing the users to data corruption.

Well or just no one ever recognised it, or those who did decided for themselves, they could live with it... > In postfix' case, it is documented like all heck, for example (see local(8) > manpage) Quote? Actually I had talked about just that lack with Wietse, too, and he didn't complain when I mentioned that there was no big fat hint in local(8) about mboxo being used and it's vulnerability to corruption. > and it can trivially be configured to use something else to > deliver mail to mbox files (such as procmail, etc). Of course, but from the postfix documentation, nothing AFAICS tells one the need to use a 3rd party MDA, because postfix' own were broken. > We [Debian] could deprecate anything that uses mboxo (mbox old) format as > the native/preferred storage format, and configure our stuff where possible > to never use mboxo by default. That's about it. That's what I've meant,... and therefore I suggested to add notice about the issue in those places where the user are most likely to read it, e.g. package description, README.Debian and depending how prone a program is to it, perhaps even via some hack like a informing debconf dialogue (though someone has indicated this might conflict the policy). E.g. Thunderbird is so much more vulnerable to it (right now) than Evolution (where at least current versions rarely use mbox, unless you import or export mail)... so for it I'd have said the inevitable debconf warning would be appropriate. Further my suggestion was, to inform users (typically via NEWS.Debian) even when the issue has been fixed already, like in getmail, what has happened over years. It's like when you have some scientific application which does wrong calculations... it's not fair to just fix it and think everything's fine now... one also has to tell people that all their previous data is likely wrong. btw: I've always thought it meant mbox original ;-) > But first, you need to get > support for better mbox formats on the important stuff. Well I guess you'll agree that this is not that easy and usually a duty for upstream. I personally, may try to invest some time into postfix, but after my struggles with the Evolution and TB upstreams, I have little interest to - sorry for the rude tone - fix their crap. Especially as it seems, well at least for TB, that mbox import/export is coded quite crude in awkwardly many places... > We [users/developers] can write patches to teach important software to use > something less retarded than mboxo by default, and pester upstream to take > them.

I think you know from your own experience, that one usually already has a big stack of projects where one is involved in... and that changes to core places of bigger projects like Evolution/TB are usually not just an hour of coding. > > If not, than the majority opinion might perhaps even convince the > > maintainers to handle this with some higher severity :) > That's not how it works.

Again, I've never asked from the Debian maintainers to write patches... My point was that we need reasonable warnings for our users, such as mentioned above. I guess such warnings are very easy to add for any maintainer, right? And as long as those are not in place, my point was, that a high severity is appropriate to give at least users with the widespread apt-listbugs a chance to notice what's going on. Cheers, Chris.
