# MMail - simple mail protocol
|
||
|
|
|
||
|
|
MMail, or Minitel Mail, is a simple electronic mail protocol for Minitel networks, using port 25.
|
||
|
|
|
||
|
|
## Messages
|
||
|
|
|
||
|
|
A message must contain:
|
||
|
|
|
||
|
|
- A line with `From: ` and an address, specifying where this mail came from, in the form of `user@host`
|
||
|
|
- A line with `To: ` and an address, specifying to whom this mail is addressed to, in the form of `user@host`
|
||
|
|
- A line with `Subject: ` and a subject line, specifying the subject of the message.
|
||
|
|
|
||
|
|
The entire exchange will be written to the file, but those lines are required.
|
||
|
|
|
||
|
|
## Sending
|
||
|
|
|
||
|
|
Sending a MMail message is simple:
|
||
|
|
|
||
|
|
1. The client opens a connection to the server on the MMail port.
|
||
|
|
2. The client sends the header, with To, From and Subject lines.
|
||
|
|
3. The client sends the message contents.
|
||
|
|
4. The client closes the connection.
|
||
|
|
|
||
|
|
The server can then decide what to do with the message.
