@copilot Ok so I think what we need to do is move to a more store-and-forward model. Where we only store the message until the client reads it. This could be problematic in the case where a user opens it across devices but I think it's probably a better idea not to store the data on the server. So essentially when the user has read the message and its stored on the client, delete it. Ensuring the user is deleting their own messages from the server including their sent items, but not the items the user they are sending to still has to read. That should mitigate some further security issues. Then the only thing to figure out is message encryption so even what's stored isn't stored in plaintext. |

@copilot try again |
Implemented store-and-forward model with AES-GCM encryption in commit 7d2453e. Key Features:
How it works:
Example encrypted storage: {
"encrypted_body": "8IShsS8uSUqqJTYaQ8tWn6S7Vi...",
"delete_on_read": true

@copilot OK so a few things. The styling is off in many places. Things are not aligned, its not great. Secondly how do I reply to mail? Nothing easy about that. Third, I think we should just auto delete after 24 hours if messages are unread. |

@copilot Everything is still totally misaligned. And it doesn't look anything like a mail client. You need to slim line everything and make sure the compose form renders properly and that everything looks good on mobile. Think Gmail. |

@copilot Ok 1. The formatting on the home page is totally messed up because you messed up my grid. Its column ordered. So you should display the mail card in top right above or below the reminder card on desktop, and then maybe at the top when its on mobile. Also the styling is still really off. On the mail page. Be consistent with the button sizing, etc. And this sort of show/hide when I hover is not good. Think about how that would work on mobile. Easier to have a little bin icon on right side. To have flatter rows. When I hit reply the compose should show the message, etc. Maybe the flow needs to be a bit more like DMs? |

@copilot Why are all the images 404ing |

All features are working as described in the PR. |





Implements an internal mail system for user-to-user messaging on the same server (no external relay). Users can compose, send, receive mail with inbox management and unread tracking. Features a clean, DM-style interface with flat rows, always-visible delete icons, and click-to-reply functionality that's fully mobile-responsive.
Core Implementation
Mail Package (
mail/mail.go)/mailendpoint with compose/inbox views?format=json) for client data accessStore-and-Forward Model
Encryption at Rest
MAIL_ENCRYPTION_KEYenvironment variableReply Functionality
Client-Side Search
DM-Style UI
Home Page Integration
Security Considerations
Encryption at Rest
Auto-Delete on Read
24-Hour Auto-Delete
No Server-Side Indexing
XSS Protection
Recipient Validation
RAG Filter (chat.go)
CSS Styling - DM-Inspired
Clean, professional CSS following DM/messaging app design patterns:
Example Encrypted Storage
Messages are stored encrypted on disk:
{ "bobuser": [ { "id": "alice-1762521997416288313", "from": "alice", "to": "bobuser", "subject": "Test Encrypted Mail", "encrypted_body": "8IShsS8uSUqqJTYaQ8tWn6S7Vi...", "sent": "2025-11-07T13:26:37.41629193Z", "read": false, "delete_on_read": true } ] }After the recipient deletes the message, the array becomes empty:
{ "bobuser": [] }Documentation Updates
Configuration
Set encryption key via environment variable (recommended for production):
If not set, uses a default key derived from a hardcoded string (not recommended for production).
Screenshots
