Blocked Senders
Block individual email addresses to prevent them from creating new issues or discussions in your repository.
Blocking a sender
On any issue or discussion created from an email, add a comment:
/block-sender
Scitor extracts the sender’s email address from the issue metadata and adds it to the block list. The sender’s email is stored as a SHA-256 hash for privacy.
Unblocking a sender
To remove a sender from the block list:
/unblock-sender
How blocking works
When a blocked sender’s email arrives:
- Scitor checks the sender’s email hash against the block list
- If the sender is blocked, the email is silently dropped
- No issue or discussion is created
- The sender receives no notification
Warning
Blocked senders will not know they’ve been blocked. Their emails are processed but quietly discarded without any bounce or error message.
Privacy
- Email addresses are never stored in plain text
- Only a SHA-256 hash is kept in the blocks table
- The hash cannot be reversed to reveal the original email address
- Block lists are per-installation (per repository)
You can still reply
Blocking only affects inbound emails. You can still use /send to reply to a blocked sender on existing issues that were created before the block.
