The new NoSpamProxy 12.3 already offers security against EFAIL even for communication partners with a weak infrastructure. Due to the far-reaching support of the new S/MIME 4.0 standard and Authenticated Encryption, many EFAIL-like attack methods are additionally neutralised. Numerous other improvements and new features ensure increased email security and increased resilience against the weaknesses of others. In our press release you can learn more about version 12.3 of NoSpamProxy, which Net at Work will present at the security fair it-sa from October 9 – 11, 2018 in Nuremberg.
Dear NoSpamProxy customers,
since a few hours we see in customer environments that send outgoing e-mails from O365 via NoSpamProxy the error “Unable to relay”. We found that Microsoft uses a new certificate to identify all Office 365 email servers, which was issued by a GlobalSign CA rather than Microsoft’s own CA. The NoSpamProxy security check to see if the server is a valid “company e-mail server” fails and the e-mails are rejected. A new Fast Channel Version is available to fix this issue.
We apologize for any inconvenience caused.
Your NoSpamProxy Team
NoSpamProxy 12.2 and Open Keys simplify key retrieval for email encryption
Among the most important new features of version 12.2 is the complete integration of Open Keys for easy querying and publishing of public keys. Open Keys is a product- and vendor-neutral service that aggregates many different key servers and thus represents a significant simplification for encrypted e-mail traffic. Open Keys offers users a central platform for querying and uploading public keys.
As of January 1,2018, many energy suppliers have converted the solutions they use for EDI message exchange to the encrypted communication required by the EDI@Energy Directive. Afterwards a significant proportion of incoming mails could not be decrypted by NoSpamProxy and was either rejected or not delivered.
On July 11th, version 12.0.17191.8 was released. This release contains the following fixes and improvements:
Net at Work presents Version 12.1 of secure mail gateway NoSpamProxy, with content disarm and reconstruction, sandboxing and open keys, on IT security exhibition it-sa (hall 13, booth 10.0-119). In addition to many small improvements and extensions, the new version offers three major innovations: content disarm and reconstruction (CDR) ensures clean email attachments, the optional sandboxing especially analyzes critical cases, and the new key infrastructure significantly simplifies the email encryption.
