Service Alert for CYREN Email Security and Spamfence

CYREN Email Security and Spamfence are currently not fully compatible to the services of the United Internet AG (GMX/web.de/1&1). Emails coming from domains with SPF (Sender Policy Framework) records are rejected by the United Internet AG due to an unexpected enforcement of SPF on their side.

We are currently working with the United Internet AG to resolve this issue. SRS (Sender Rewriting Scheme), a technique that rewrites the sender of an email in a way that SPF also works with mail forwarders, seems to be the obvious solution to the problem. Unfortunately, it has certain negative side effects which render this method almost unusable for mail forwarders like us.

Until a solution has been found we recommend turning off SPF checks on your side if possible. Spamfence users may use a different destination address for emails forwarded by Spamfence.

Update: as of June 10, 2016 the issue is resolved.

Scheduled maintenance - CYREN UK Data Center

The maintenance was completed successfully.

As part of the maintenance we have changed the UK Data Center IP addresses. This change should be transparent to most customers using this Data Center as CYREN client will automatically resolve the new IPs. In cases where customers use IP addresses instead of DNS resolving of the ServerAddress, and in cases where there are firewall restrictions for connections between CYREN Engine and the CYREN Data Center, the IP addresses should be updated according to the information below. Please note that CYREN recommends using the DNS names for ServerAddress and not specific IP addresses.
