Improvements for phishing warning
We would like to warn the user when a new sender looks like a known contact. Looks like means:
- Similar display name but different mail address
- Typos in domains (e.g. https://github.com/elceef/dnstwist)
- Same identifier but different domains
We can also check the DKIM state (see #244). We cn also discuss to implement other ideas, e.g. from security guidelines or other tools.
-
Add more communication channels (call, IM etc.) -
Consider display name for phishing detection -
Consider similar display names, similar mail addresses(just for completeness)
This issue should be split in more handy issues.
