In many situations around the world in developing countries, it is
totally impossible to send a 10MB e-mail because the link will be at
least break once in the time it takes to send 10MB. As e-mail does not
resume...
FWIW, RFC 1845 specifies such a mechanism for SMTP. There have been
few implementations, however.
There are still many countries which only connection to the Internet is
a 64kb/s and quite a lot which speed is below 512kb/s
Developed countries and the IETF need to cater for these emerging
nations to avoid the digital divide.
I think as yahoo being a major e-mail provider it would be good, that
they become more responsible (they are actively fighting SPAM) and use
ESMTP when sending their e-mails. It seems they do use ESMTP to receive
e-mails...
ESMTP in general and the SIZE extension in particular do offer
some significant advantages in such situations.
