I'm looking for a mail client that supports handling rather large IMAP folders and that can ignore notifications for specific subfolders.
I'm an old Mozilla Mail user and obviously I migrated to Thunderbird a long time ago. However, the lack of response to filed "bug reports"/requests about re-enabling server side search instead of local search in combination with a complete lack of support for disabling notifications for specific (sub)folders has made me go for a hunt.
Does anyone know any decent client for Windows and OS X for this? I am actually considering making a branch of Thunderbird or try to patch up old Mozilla Mail again. This is crazy. ;-)
