That  depends  on  what  kind  of rejection the provider is enforcing.

AFAIR,  MS  SMTP  and  Postfix,  for  two examples, will automatically
re-queue  remaining  recipients if a "neat" rejection (4xx, preferably
452) occurs after a RCPT TO:. However, if the ISP is actually dropping
the  SMTP  connection  entirely  at  that point (5xx) or resetting the
connection  at  the  TCP/IP  level,  that will be fatal for the entire
session.

I  believe  MS  SMTP  can also be configured, with some fancy loopback
between virtual domains, to ensure that no more than 50 recipients are
ever _attempted_, which would solve your problem but would be a second
resort.
