I think the only answer at this point is, "upgrade to latest FW."
- Fix: SSLv3 has been disabled in the Web interface to mitigate CVE-2014-3566 (SSL POODLE). [BNSF-22788]
- Enhancement: New setting on ADVANCED > Email Protocol page to allow or disallow SSLv2 and SSLv3 for incoming SMTP connections. Setting to Yes provides for greater compatibility with older mail servers. Set to No to mitigate the recently reported SSL POODLE [CVE-2014-3566] issue. [BNSF-22788]
- Fix: Resolved an issue in the encryption module that affected transmission of outbound messages over a TLS connection to some types of mail servers. [BNSF-22782]
That said, we're having a weird issue with it, but nothing game-breaking. In our outbound quarantine, we can't open attachments directly, but have to download the entire message, open the .eml file, and open the attachment from there. Apparently, this is NOT normal (or intended, obviously:), from what Support has said, so I'd assume you won't experience this.
