We have an Ironport C160 on Async OS 8.5.6-106. I know it's outdated- we're investing in VMWare infrastructure later this year but for now we're still on the C160.
In recent months we're feeling like the C160 is letting a lot more spam through than normal. I noticed that its CASE core files and utilites date back to August 2015. I believe this is because our unit is no longer supported as far as those updates are concerned. Is that correct? Could the outdated CASE files be responsible for the spam getting through? All my other rules / updates are up to date.
If I were to purchase a used C170, can I transfer my existing subscription to that unit? Is there a fee? How do I go about doing that?
