to use IPoMC:
Step 1:
go to a IPoMC mailbox and place a minecart chest on the unpowered rail

Step 2A:
starting from the top left, fill the minecart with the correct combination of sugar and sugarcane for the targeted address

Step 2B:
getting the proper combination of sugar and sugarcane is quite trivial, 
take the first number of the address (each number is seperated by a '.') 
and put, the first number minus one, sugar in the minecart
then put one sugarcane in afterwards to confirm the number
(for example if first number was 6 then you would put 5 sugar and one sugarcane in the cart)
then keep repeating the process for each non zero number in the address
(if a number in the address is zero you can skip that number)

Step 3: 
fill the minecart starting from the bottom right with the contents you wish to mail

Step 4:
press the button to send the minecart
