Bug#696301: preapproval unblock: dspam/3.10.1+dfsg-6

[Thomas Preud'homme <robotux@celest.fr>]

Package: release.debian.org
Severity: normal
User: release.debian.org@packages.debian.org
Usertags: unblock

Please unblock package dspam as it fixes bug #695275 of severity
serious:

src:dspam: harmful actions in multiple postrm scripts of M-A:same
packages

The proposed patch is to detect through dpkg-query if this is the last
instance of libdspam7 to be purged and only lock dspam user account if
it is the case. The detection is made by counting the number of packages
not purged (not installed are not considered) excluding the currently
being uninstalled package. See debdiff attached.

My proposition for more testing is to first upload the fix in unstable
and then after 10 days do the upload in tpu (version in unstable is not
the same as in testing). Is this procedure fine for you?
