That's not the worst part of the license. The real problem is that
qmail as written has several logical flaws, the above-mentioned
being the most obvious, and the license states that no one is
allowed to distribute modified versions so it can't be fixed
without completely replacing components.
There is a slight workaround. One can distribute the original + source
+ patches and a script that does the patching/installing. Hence the
netqmail-1.05 version.
Les, quit making false statements about qmail. qmail does not have any
logical flaws otherwise Wietse would not follow the same design
principles in postfix after his spat with DJB. qmail's problem is that
the author has not done any updates to it since 1998 to handle the
changed needs required of a MTA software since then. SMTP is broken
which is why spammers and virus writers can create so much trouble.
Both SMTP and qmail were designed in an environment very different
from what we have now. That is why we have ESMTP and what not updates
to the SMTP protocol.
qmail is a fine piece of software and it also introduced the maildir
format which is now widely supported and used by anyone who cares
about the integrity of their mailboxes. I cannot understand what you
have against qmail to go around bad mouthing it. Don't tell me a
stuffed queue and perhaps a listing in some over zealous RBL was all
it took.
And what exactly does any of this have to do with CentOS? Personally, I
dumped qmail back in the 90's when it became apparent what a flaming
horse's hiney DJB was. Wietse has been a lot easier to deal with, quick
with patches, and just an overall nice fellow. So I've used postfix
since 98-ish without incident and still use it today. It's fast, easy
to configure, and it is well supported by Redhat (and by extension) and
CentOS (see, this is sorta on topic now). So while I could go through
all these gyrations to make qmail work...blah blah blah....why should
I? If you'd like to continue this, I'd be happy to do it off list.
Cheers,
Chris
