I'm not sure / don't care (for the sake of discussion) who does the
splitting. I was just implying that the first server should accept
things as they come in (don't enforce splitting by failing additional
recipients) so as to be compatible with as many MUAs / MTAs as possible.
Have either the first server configured to send individual recipients
to the second server, or the second server configured to temp fail
additional recipients thus causing the first server to resend Temp
Failed recipients. However it would be even better to configure
Sendmail to speak LMTP between the first and second server so that the
message from the first server could be transfered to the second in one
transaction for all recipients in such a manner that the second server
could filter and respond accordingly for each individual recipient.
This would allow for transferring messages in <size>+<overhead> fashion
verses the <number of recipients> * (<size>+<overhead>) that would be
required for multiple transactions.
