This is related to text lines in the mail-body. The relevant part is below
(from RFC 821) :

recipients buffer

The maximum total number of recipients that must be
buffered is 100 recipients.

That means if your mailserver support it (as it should according to RFC)
you can have more than 1000 RCPT-TO. By sending it the mailserver than have
to split this to chunks the remote can handle.

BTW : You should not send lists with all addresses in RCPT-TO because of
privacy anyway.
