Sophos Email Appliance - Spam still getting through

jadedmia
We are using Sophos Email Appliance (latest patch) and according to Sophos we have everything configured the best way to block spam. Still continuing to recieve spam to users inboxes. Really blatant stuff like free gift cards and things like that. Anyone have any ideas on how to stop it? It seems like since about Febuary 2014 a lot more spam is getting through and being marked in the logs as legitimate. I have checked the allow lists and I don't have anything listed that it could be bypassing the policies.

Any help would be greatly appreciated because it seems to be from Sophos's last correspondence that they are basically unwilling to help any further.

    We also have been hit hard by spam, so much that I was told to find a new option.  I called support and was told I had it all configured correctly.  After downloading another vender's trial spam filter appliance our snowshoe spam was blocked completely.  The 2 features I feel made the difference were a delay feature when too many emails come in from the same address in a set amount of time and the ability to use RBL.  I added zen.spamhaus and a couple others and according to their logs about 30%-50% of spam are blocked because of those lists.  Unfourtunetly their encryption options are poor so I'll be continuing my search.  I may, however update my Sophos email appliance to see if that makes a difference.  It's so suprising that they have so many options to customize encryption but all anti-spam has is just "high" or "medium" and that's about it.  Getting in to block a /24 every morning isn't really going to be the best option.
