And there are still *many* problems remaining. It's a very shoddy program IMHO, and the "fixes" are merely bandaids while the real problems remain. It's string handling and termination really sucks. If *just one* spot was missed, the holes are still there to exploit all over again. > Cucipop may be a bit better, but why *whack* do you even *whack* > ASK *whack* *whack* ! :-) The cucipop code style scares the hell out of me, but it's bloody fast and dots all the i's and crosses all the t's etc - I'd be rather suprised if major holes were found. It has a few bugs that are a bitch to track down (see previous gripe about code style), but nothing serious. It's mainly a cosmetic glitch where it announces the per-message size a few bytes too large and fetchmail complains about that. It doesn't know about expired passwords either. It's got some really devious features too.. :-) You can sabotage the UIDL command to strongly "encourage" your users to NOT keep mail on the server forever, and do all sorts of things like auto-delete old (read) messages etc. (The UIDL sabotage means that if they select "leave on server", they'll get another "new" copy of each message each time they connect.) > -- > -[ Philippe Regnauld / sysadmin / regnauld@deepo.prosa.dk / +55.4N +11.3E ]- > > The Internet is busy.
