Z1 SecureMail Gateway is a central, server-based software solution that provides encryption and digital signatures (PGP and S/MIME) for the entire email traffic of an organization. It works with organizational certificates and certificates for individual users, groups, or organizational units. It provides its services transparently to end users. Z1 SecureMail Gateway automatically finds certificates of external users or companies via Internet. Secure email traffic to customers, suppliers, and partners is easily established. Evaluation packages for Debian and Solaris are available for download.

Recent releases


Changes: This release adds a new data model for the administration of both internal and external mandators, domains, groups, and users. The majority of the settings, policies, keys, and certificates can be set at each level of the model. It also offers flexible administration of multiple key-certificate pairs and their management policies; e.g these define when and which keys or certificates should be issued or revoked. User certificates are optionally exported into LDAP directories and/or into “Z1 Global TrustPoint”. An option has been added to centrally attach disclaimer to all outgoing email messages.


Changes: An enhanced new group feature was provided. Groups may contain single members (e-mail) or domains (wildcard), and policies can now be assigned to groups. The usability of the Admin Webclient was improved. A new user confirmation feature was introduced to protect outgoing sensitive operations like signing e-mail. New user commands were added for sending reports. PKCS#7 attachment validation was implmented, which verifies signed attachments and generates validation reports similar to GDPDU. An "e-mail-copy-to" feature that duplicates all incoming e-mails and sends them to a specific SMTP server (e.g. e-mail archive) was added.


No changes have been submitted for this release.


Changes: The architecture was changed to separate the old certserver from Z1 SecureMail. The new name of the certserver is Z1 Backbone CertServer and comes as a separate project. "Unison" now replaces "rsync" for the synchronization process of configuration files. A header line called "X-TBoneMailStatus" was added for incoming email messages, which contains the verify and/or decrypt status of email messages, similar to the footer.


Changes: Improved external certificate search: the search is now performed in parallel for each recipient if a message has multiple recipients. Improved performance for traffic/security statistics. The Message-ID Header is now included within the statistic database. The Z1 SecureMail mail log will now indicate if an encrypted message could not be decrypted because no suitable secret key was found. The checking routine for some encoded OpenPGP attachment names has been fixed. Previously, these were not recognized as OpenPGP attachments at all.
