[Pkg-dspam-misc] Bug#411995: dspam: LocalMX attribute doesnt work with non global shared group

[Etienne PENICAUD]

Package: dspam
Version: 3.6.8-5
Severity: important

Hello,

My dspam is configured with shared groups, one global and other are normal.
When i send a message for a global group user, LocalMX is used.
But when i send a mail for a normal group user, dspam don't care about 
this attribute.

I've my dspam check behind an antivirus mail relay , so all my local 
mail relay tokens have a high spam probability.

Other checks :
- when i try with only one normal shared group in the config file, the 
problem is same.
