(1) are you using the driver API =3F
(mailstorage / mailfolder / mailmessage)

(2) or are you using the low-level POP3 API =3F

1. the driver API will provide the cache for you.

2. in the low-level API, you can get the information of the message.

int mailpop3=5Fget=5Fmsg=5Finfo(mailpop3 * f, unsigned int index,
                           struct mailpop3=5Fmsg=5Finfo ** result);

struct mailpop3=5Fmsg=5Finfo =7B
  unsigned int msg=5Findex;
  uint32=5Ft msg=5Fsize;
  char * msg=5Fuidl;
  int msg=5Fdeleted;
=7D;

msg=5Fuidl will be a unique identifier for the message and it will be kep=
t=20
between two connections.
