Now that I think everything work ok, mail doesn't diappear, etc.:
Update to dspam-3.4.5
This is the post-3.4 devel branch. A lot of things have changed and your
existing dspam.conf won't probably work anymore. Please compare it with the
dspam.conf.sample located in the same etc/ directory.
Most notable addition is the SMTP delivery which together with "standard"
inbound LMTP make a very nice content and light (e.g. it's the fastest setup
I've had so far) filter.
Database structure is roughly the same but you may wish to check your
existing database structure with the *.sql corresponding to you database
driver from EXAMPLESDIR (Mysql 4.1.x is now default as it's _much_ faster).
Please read carefully distributed docs like README and UPGRADING.
