AFAIK, all services such as that are stated in bits, and are a
theoretical maximum.

So your figures would be divided by 8, thus probably no more than 3 - 4
messages per second.
30k (bytes)  would be about 240k (bits)
Thus 3 messages (720k (bits)) per second of that size would be
stretching it after factoring in the overhead for an 800k pipe.

Sending that volume of messages of that size is VERY inefficient, and
that also is why we complain loudly when our mailing list is sent html
mail.  A 30k html mail would likely be 1k or less as text.
