About the junkmail folder I think you forgot to include the following icon:
/usr/lib64/GNUstep/SOGo/WebServerResources/tb-mail-junk-flat-17x17.png At least in the centos6 64 bit packages. I get 404 for:192.168.1.78 - - [26/Jan/2016:11:52:03 +0100] "GET /SOGo.woa/WebServerResources/tb-mail-junk-flat-17x17.png HTTP/1.1" 404 319
Also the junkmail folder is shown as "JunkFolderName" in the web interface -- [email protected] https://inverse.ca/sogo/lists
