Indsæt mail i MySQL

Jeg tror du skal prøve med et mere konkret spørgsmål, hvis du vil have svar :)

Du kan vel gemme selve E-Mail'en (*.eml format) direkte i databasen som en BLOB => Binary Large OBjects

e256. Getting BLOB Data from a Database Table
A BLOB is a reference to data in a database. This example demonstrates how to retrieves bytes from a BLOB.
    try {
        Statement stmt = connection.createStatement();
        ResultSet rs = stmt.executeQuery("SELECT col_blob FROM mysql_all_table");
   
        if (rs.next()) {
            // Get the BLOB from the result set
            Blob blob = rs.getBlob("col_blob");
   
            // Get the number bytes in the BLOB
            long blobLength = blob.length();
   
            // Get bytes from the BLOB in a byte array
            int pos = 1;  // position is 1-based
            int len = 10;
            byte[] bytes = blob.getBytes(pos, len);
   
            // Get bytes from the BLOB using a stream
            InputStream is = blob.getBinaryStream();
            int b = is.read();
        }
    } catch (IOException e) {
    } catch (SQLException e) {
    }
