No, it really should be MIT licensed ("as per qpsmtpd") to go in the distribution.
There are a few exceptions (only your plugins at a cursory glance), but those are mistakes. :-)
I don't have an issue with my qpsmtpd plugins being changed to state:

This software is free software and may be distributed under the same

Though as a distro maintainer, we do have a sizeable issue with license proliferation. It really is a bit of a nightmare when two licenses are almost, but not completely, the same.

o plugins/check_badmailfromto
- New plugin in the style of check_badmailfrom, which matches a pair
of FROM/TO and makes it seem like the recipient's address no longer
exists (but only from the matching sender's point of view). Useful
for stalkers and other harassment cases.
o plugins/dns_whitelist_soft
- New plugin to provide a DNS-based whitelist (good for distributed
sites).
o various files
- Replaced tab character with 8 spaces and adjusted line breaks for
better readability.
Changes by mct@toren.net (Michael C. Toren)
o lib/Qpsmtpd/SMTP.pm
- Assumes a MAIL FROM value of "<#@[]>" (utilized by qmail to
indicate a null sender when generating a doublebounce message)
is equivalent to "<>". Previously qpsmtpd complained that the
value could not be parsed.
- Adds LOGIN to the default list of supported auth mechanisms.
The documentation in Auth.pm indicated that auth-login was not
currently supported due to lack of functionality, however I can
confirm that LOGIN appears to work fine as tested by using msmtp
(http://msmtp.sourceforge.net/). Are there any indications that
LOGIN support is actually broken in the current implementation?
- Removes the "X-Qpsmtpd-Auth: True" header appended when a message
has been sent by an authenticated user. One problem with such a
header is that it's impossible to say which SMTP hop added it,
and it provides no information which could be used to backtrack
the transaction. I grepped through my mail archives a bit
looking for how other MTAs handled the problem, and decided it
would be best to place this information in the Received: header:
Received: from remotehost (HELO remotehost) (192.168.42.42)
(smtp-auth username foo, mechanism cram-md5)
by mail.netisland.net (qpsmtpd/0.28) with ESMTP; <date>
o lib/Qpsmtpd/Auth.pm:
- Documentation update for the arguments passed to an auth
handler; previously the $mechanism argument was not mentioned,
which threw off the argument offsets.
- Documentation update for auth-login removing the warning
that auth-login is not currently supported due to lack of
functionality.
- Fix to execute a generic auth hook when a more specific
auth-$mechanism hook does not exist. (Previously posted
to the list last week.)
- Upon authentication, sets $session->{_auth_user} and
$session->{_auth_mechanism} so that SMTP.pm can include them
in the Received: header.
o plugins/queue/qmail-queue
- Added a timestamp and the qmail-queue qp identifier to the
"Queued!" 250 message, for compatibility with qmail-smtpd, which
can be very useful for tracking message delivery from machine to
machine. For example, the new 250 message might be:
250 Queued! 1105927468 qp 3210 <1105927457@netisland.net>
qmail-smtpd returns:
250 ok 1106546213 qp 7129
Additionally, for consistency angle brackets are placed around
the Message-ID displayed in the 250 if they were missing in the
message header.
o plugins/check_badmailfrom:
- Changed the error message from "Mail from $bad not accepted
here" to "sorry, your envelope sender is in my badmailfrom
list", for compatibility with qmail-smtpd. I didn't see any
reason to share with the sender the value of $bad, especially
for situations where the sender was rejected resulting from a
wildcard.
o plugins/check_earlytalker:
o plugins/require_resolvable_fromhost:
- No longer checks for earlytalkers or resolvable senders if the
connection note "whitelistclient" is set, which is nice for
helping backup MX hosts empty their queue faster.
o plugins/count_unrecognized_commands:
- Return code changed from DENY_DISCONNECT, which isn't valid in
an unrecognized_command hook, to DENY, which in this context
drops the connection anyway. (Previously posted to the list
last week.)

Subject: HELO hook and check plugin
Speaking of direct-to-MX spam, both AOL and Yahoo are large companies
with whole walls-full of servers devoted to mail delivery. None of them
announce themselves with "HELO yahoo.com" or "HELO aol.com." Spammers
certainly do, though.
Here's a patch to SMTP.pm to add hooks for HELO and EHLO, and a plugin
to use them.
