(1) are you using the driver API ?
(mailstorage / mailfolder / mailmessage)

(2) or are you using the low-level POP3 API ?

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_get_msg_info(mailpop3 * f, unsigned int index,
                           struct mailpop3_msg_info ** result);

struct mailpop3_msg_info {
  unsigned int msg_index;
  uint32_t msg_size;
  char * msg_uidl;
  int msg_deleted;
};

msg_uidl will be a unique identifier for the message and it will be kept 
between two connections.
