Hello,<\/span><\/div>\n

\n<\/span><\/div>\n
We noticed that your domain is sending email to Gmail users that is DKIM signed with a 512-bit RSA key. RFC 6376 requires DKIM \u00a0 \u00a0 \u00a0 signing mail using RSA keys of at least 1024-bits for long-lived keys (https:\/\/tools.ietf.org\/html\/rfc6376#section-3.3.3). Shorter \u00a0 \u00a0 \u00a0 \u00a0 keys could be factored by an attacker. As you may know, this attack has been publicly reported. US-CERT has also issued an \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 advisory to upgrade all keys lower than 1024-bits (http:\/\/www.kb.cert.org\/vuls\/id\/268267).<\/span><\/div>\n

\n<\/span><\/div>\n
As such, we strongly encourage you to upgrade your RSA keys to be at least 1024-bits long.<\/span><\/div>\n

\n<\/span><\/div>\n
To best protect our users, Gmail will begin treating emails signed with 512-bit keys as unsigned in about a week. If you continue to use your current key, your messages will not DKIM authenticate.<\/span><\/div>\n

\n<\/span><\/div>\n
Affected key:<\/span><\/div>\n

Thank you,<\/span><\/div>\n
