We give security-related reports their own priority, because behind a discovered problem could be the security of hundreds of thousands of mailboxes.
Please use this form only if it is a security-related problem. General support, for example software malfunctions, will be handled through our ticket system.
However, we would like to handle security problems separately in order to resolve them as quickly as possible. We are dependent on your assistance in this regard. If you notice a security problem while using our software, please do not hesitate to report it to us.
The fastest way to send us your report is to fill out this form and click SEND.
