(keitai-l) emailing limitation

hi,

anyone got an overview on the various email solutions provided by the 
carriers? i need to know the max number of attachments one can send and 
receive and how big they can be (each and combined). au seems to be 100kB 
total when sending and 100kB for each attachment when receiving. how about 
jphone and docomo (505 and foma)?

thanks and regards, tmk
