The REDDOXX MailSealer is the security solution for your e-mail traffic. Outgoing emails are signed and encrypted, incoming emails are checked and decrypted. MailSealer supports the internationally established encryption standard S/MIME and is therefore compliant with other solutions used by your communication partners. Encryption and signing are rule-based and therefore centralised and automatic - user-independent.
S/MIME stands for Secure / Multipurpose Internet Mail Extensions. It is the worldwide established standard for the encryption of e-mails - based on a hybrid cryptosystem. The use of S/MIME requires corresponding certificates with which the contents of an e-mail can be reliably encrypted by the sender and then decrypted again exclusively by the authorised recipient.

| - Optional clear text signing | ||
| - Optional signing before encryption | ||
| - Optional inclusion of the sender key | ||
| - S/MIME certificate retrieval from LDAP directory service | ||
| - signature encryption: MD5, SHA-1, SHA-256, SHA-384, SHA-512 | ||
| - different signature algorithms: RSA, RSASSA-PSS | ||
| - supported encryption algorithms: RC2 (40, 64, 128 bit), DES (56 bit), 3DES (168 bit), AES (128, 192, 256 bit) | the encryption depths can be freely selected depending on the algorithm | |
| - certificate encryption algorithms: RSA, RSAES-OAEP | ||
| Free definable set of rules | ||
| - outgoing signature rules per mail address, mail domain | definition via wildcards for sender and recipient addresses | |
| - outgoing encryption rules per mail address, mail domain | the definition is made via wildcards for sender and recipient addresses | |
| - use of gateway certificates | requires a corresponding function on the remote terminal (recipient) | |
| - Validation of the signature for incoming mails | E-mails with invalid signatures can optionally be rejected | |
| Certificate management | ||
| - optional use of own CA with automatic issuance of e-mail certificates | in this case, the remote peer must recognise the ROOT-CA | |
