Summary: BUG in DSPAM?
Initial Comment:
Hi there,
today I was debugging some problems with DSPAM and I found this:
BUG in DSPAM. Please report this bug:
--> Skipping merged group spam: user [dspam-user] is already in merged group
I'm using DSPAM in daemon mode with PostgreSQL server - latest GIT version.
Here is my configuration string: ./configure --prefix=/usr --sysconfdir=/etc
--with-dspam-home=/var/dspam --with-logdir=/var/log
--with-storage-driver=pgsql_drv --with-pgsql-includes=/usr/include/postgresql
--enable-preferences-extension --enable-large-scale --enable-daemon
--enable-virtual-users
My group file has only one line:
spam:merged:*
Here is a full debug from an example connection:

Does this "BUG" can cause real problems?

Hi again Stevan,
I had to examine in depth the problem with "BUG in DSPAM". It seems that in
my configuration (take a look above again) it does matter a lot. I receive
this error on every message that was addressed to more than one receipient
on my system. From my short examination it seems that the agent context
flag DAF_MERGED should not be used as agent context wide flag. As I
understood from the code it supports just the logic implemented in ctx_init
procedure and nothing more. But the agent context wide implementation is
causing the problems as described above.
When I add the code to reset the flag at the beggining of the ctx_init
procedure system is working as expected. Please advise if I am on right
track here...
Code (dspam.c - ctx_init):
----
int is_group_member_inoculation = 0;
int is_group_member_classification = 0;
int is_group_member_global = 0;
int is_group_member_shared = 0;
int is_group_member_merged = 0;
char *group;
char buffer[10240];
// NDA FIX - clear DAF_MERGED from agent context flags
ATX->flags &= ~DAF_MERGED;
while (fgets (buffer, sizeof (buffer), file) != NULL)
----
Thanks for all the support you provided so far for the community of DSPAM!

Thanks I though so looking at the code...
[dspam-user] is just a common reference to real user - I simply replace the
real one with this. :)

Not really. It is more or less informational. The code is not doing any
harm. Just printing that this (in theory) should not happen and therefore
it must be a bug in DSPAM.
I will need to look into that later.
btw: Have you really named your DSPAM User "[dspam-user]"? Why? Why the
brackets and especially why that dash?
