ReceiverInfo
Every receiver is stored in Redis as a JSON value with the mail address as key. The JSON value has the following structure:
{
"mailStorageGuid": "b8187230-ced6-48f9-957a-6a76b4250d8a",
"attachementStorageGuid": "33250880-d59e-4513-8f54-d5edb0ea3957",
"knownNames": [
"Hans Dampf",
"Rainer Zufall"
],
"lastMailReceived": ".NET DateTime format",
"totalMailsReceived": 42
}
The property mailStorageGuid is used to resolve a hashset containing all mails the user has already received.
See ReceivedMail for further information.
The property attachementStorageGuid is used to resolve a hashset containing all attachements informations the user has already received.
See AttachementsInfo for further information.
ReceivedMail
Every received mail is stored in the mail storage of the receiver. Every time MailHole received a mail it assigns a GUID to the mail and stores the mail under this GUID in the mail storage of the receiver.
The received mail has the following structure
{
"sender": "any@one.com",
"bcc": [
"another@one.com"
],
"cc": [
"andAnother@one.com"
],
"subject": "subject of the mail",
"htmlBody": "<html><body>you know...HTML</body></html>",
"textBody": "yeah...the text body of the mail",
"headers": {
"header1": "and its value"
},
"utcReceivedTime": ".NET DateTime format",
"attachementsGuid": "f068d581-3ff3-478a-8681-b0c203416be0"
}
If the mail had attachements the property attachementsGuid will be set to a GUID that can be used to lookup the attachements information in the attachements storage of a receiver.
See AttachementsInfo for further information.
AttachementsInfo
The attachements information entity contains all information about a single mail attachement.
It is stored as a JSON array in the attachements storage hashset of a receiver at the attachementsGuid key.
The entity has the following structure:

}
]
Where fileSize is the size in bytes.
The other properties should be clear.
