Recent updates of EasyMail have large red icons that match the default UI wonderfully but clash terribly with Aurora/RealUI. I've made some quick and dirty reskins in Gimp. This is just a reskin, so no class colored highlights or anything fancy like that. Art assets used include the images from EasyMail as well as Aurora Missing Textures. All thanks goes to their respective authors.
To install, unzip the folder. Copy the images folder to the EasyMail folder and override everything.
