Some clients might send MS documents, some not, subnetwork based - Why?

[Götz Reinicke - IT Koordinator]

Hi,

we have a basic setup for amavis which dose a good job so far. Recently
we decided to drop MS documents and I added a rule for the filename
extensions.

So far so good, lookend good.

But now we have some users which can send docs/excel files internal, and
some not.

E.G. a user from 172.17.25.0/24 cant send. A user from 172.17.22.0/24 can.

May be someone can give me a quick hint where to look and what to adjust
so all internal users might send docs.

        Thanks and regards . Götz Reinicke
