So a customer tested the current mailviewer and they would like the following changes regarding file save as / save as decrypted:
- Decrypted mails should default to .eml file extensions.
- Alternative offers should include .mime and .mbox
- Encrypted mails should default to .mime
- Alternative offers should include .p7m (for S/MIME only)
- Alternative offers should include .eml and .mbox
As a filename suggestion the subject should be used if this creates a valid filename. If not either a sanitized subject or no suggestion.
