Starting on June 19th around 21:26 UTC we have been observing a number of temporary errors while establishing TLS connections to some servers. We identified this issue to be caused by an error in the implementation of TLS 1.3 in the mail server software which is used by a part of our outbound infrastructure for Cyren Email Security. You might have received some temporary error messages or delay notifications when trying to send email.
We implemented a workaround until a new version of our mail server software can be rolled out.
