Our small office has a Mac Mini running SL server for a low hit website, a handful of mail accounts (IMAP) and file server. It was set up using the guidelines at Lynda.com (if anyone is familiar). The machine is serving us well with the exception being its handling of junk mail. The first issue is that junk mail with just an image or an image with small amounts of text doesn't get blocked. We do have junk mail and not junk mail accounts set up where junk mail that gets through is redirected manually from local machines back to the server but we haven't noticed the server learning what is junk. Is there a way to fix this? The second issue is that the server doesn't seem to block any junk mail when mail is checked on a mobile device like an iPhone. For example: incoming junk mail --> server --> local machine. About 60% of the junk mail is redirected to the local machines junk mail folder but image spam gets through to inbox. incoming junk mail --> server --> mobile device. All junk mail ends up in the inbox of mobile device. Any ideas to correct this issue would be greatly appreciated.
