fixed 8.13.8, but like so what. Sendmail spawns new processes. DOS one process and another will open for the next mail request. For sendmail you can only DOS the spawn you opened.


They also seem to forget that sendmail accounts for 60% of the worlds MTA, qmail probably 35% and the rest 5%, now when postfix grows to a large userbase, its going to be a sure thing many bugs and dangerous security holes will be found.

Here's an article from O'Reilly that suggest a somewhat different distribution.
