Snowshoe Spam Campaigning

jparocua
Hi,

I'm currently using the Sophos Virtual Email Appliance for email filtering.  As of late, we have had terrible luck with a lot of SPAM getting through.  We've identified this SPAM as snowshoe.  

My question is the following.  Can you please provide your experience with SPAM, specifically with snowshoe SPAM?  Are those of you using the UTM product seeing a lot of SPAM coming through your filter?  

Just for comparison, I'm seeing about 100 SPAM messages coming through our filter (From Oprah, to Slim down, to Mortgage rates, to Russian women)

I'm trying to gauge whether I should be switching to the UTM product, or another vendor altogether.

Thanks!

    I'd like to help, but we've not seen any snow shoe, oprah messages over here.

    However, we have had a lot of success with the anti-spam side of the UTM. 

    SMTP last 24 hours [ 5164 messages delivered. 3519 messages blocked (40%) ]

    Malware quarantined/rejected:	2		SPF rejects:	7

    Spam quarantined/rejected:	331		RBL rejects:	774

    Blacklist rejects:	109		BATV rejects:	32

    Address Verification rejects:	0		RDNS/HELO rejects:	2264


    We sometimes see 0 day spam hit a few boxes and then be blocked within an hour.

    Thanks for sharing that information.  Sounds like this is worthwhile.

    hi,

    We are having the same issue as jparocua. Lot of SPAM coming since we have update our SG210 UTM to  9.305-4. I think that RBL is not working also.
    Here our stats:
    SMTP last 24 hours [ 6631 messages delivered. 637 messages blocked (8%) ]

    Malware quarantined/rejected: 1 SPF rejects: 5
    Spam quarantined/rejected: 0 RBL rejects: 0
    Blacklist rejects: 0 BATV rejects: 226
    Address Verification rejects: 405 RDNS/HELO rejects: 0

    If you see the percentage of block is very low... we are use to have arround 50% or more.

    Any proposal to have the function working back correctly will be appreciate!
