Following describes the format of xfer files, which are located in the roots
of user folders, and contain the information about mail transfer feature for
users

Files are a sequence of following records:

  string64=string[64];

  TXFerRec = packed record
    Version: Integer;
    SMTPServer: string64;
    SMTPAuthentication: boolean;
    SMTPUserName: string64;
    SMTPPassword: string64;
    SMTPMailFrom: string64;
    SMTPRcptTo: string64;
    SMTPKeepCopies: boolean;
    POPServer: string64;
    POPUserName: string64;
    POPPassword: string64;
    POPKeepCopies: boolean;
    Reserved: array[0..127] of Char;
  end;


Integer takes 4 bytes.  Version is currently not used,and is 0. Boolean takes 1 byte,
and is 1 for true, 0 for false.

string[n] takes n+1 bytes.  0th byte of a record is an actual length of string.

For example, string[6], which contains the string "test" (without quotes) will be
represented as

04 74 65 73 74 00 00

Last two 00 00 can be any random value.
