Unable to download spam emails in outlook

[Chewza]

Tested on Centos 7 with a little modification, and WORKS!!!
I test it with different mail account and confirm that it works

If someone interested on how to on centos, i can post, but its no big difference from @diablo

The only problem - request is that i can see spam on "ROUNDCUBE" on spam folder, but spam messages never downloaded to local windows mail ( outlook )

I try a lot of changes, still spam stuck on vps roundcoube and never downloaded on local pc outlook
Any help?

I'd be interested in seeing what your steps are to see if we can figure out what's going on with roundcube.
