submit spam to sophos? UTM not blocking enough

JasonIstre
I have added additional blacklists, turned on strict RDNS, but my users still are each still reporting 5-10 spam messages making it through everyday.  There has even been a virus or two slipping through every month.  Is there an easy way they can submit to Sophos without having to do a new email and attach the spam message?  I see recent Sophos articles like this...

Submit a Spam Sample
and
How to submit spam messages to Sophos with the Outlook Add-in

...which mention an outlook addon, but it appears that is regards to SEA or SEG or some other sophos email protection products.  I'm confused on the product lines, Is UTM email filtering a legacy/inferior Sophos product they are moving people away from?

    Hi Jason,

    Not exactly answer to your question/problem but consider implementing two layers of AV/AS defense, one on UTM and another on your internal mail server. Don't rely only on gateway SMTP protection, your internal mail flow is also vulnerable.

    Example from the field:

    DNS MX record -> UTM (Avira single scan, spam config very loose) -> EXCHANGE (Sophos Pure Message for Exchange, very restricted policies with user quarantine scheduled e-mail enabled).

    The Spam filtering on the UTM is still using the Commtouch (now named Cyren) system (no changes to that in years) ... not sure what the "classic" Sophos Anti-Spam appliance uses.

    hi guys, 

    i´ve recognizing a similar problem. Mails went through the UTM, especially with .zip attachments and won´t blocked. If saving the mail attachment to the clients local disk, our sophos virus scanner detect the virus/malware file at once and cleans/quarantines it.
    Recent FW has been applied, but this happens one/two times a week since two-three month ago
