- S/MIME Compression is a component of S/MIME to reduce the message size and encryption processing time. It is only effective if the message has a very long text or is signed/encrypted and internal attachment encoding is "binary"
- Password based encryption, compression and binary encoding may not be well supported by other email clients which support S/MIME and may cause problems. Please test before real use
- PGP is not supported but in planning
