SMTP is supposed to support a minimum of 50 addresses for a given
message. It is not guaranteed to go higher than that. Although
SPAM filters and hosting servers may not honor that, it's a good
start. Some UNIX servers may not honor a command-line length longer
than 10K or 20K, which will be violated with 6000 users.

Try testing it. This is really the only way to be sure.
Note that your host may not be the only one enforcing limits. If,
for example, you send to 1,000 addressees, your host might accept
that, but if there's 60 in that batch going to sol.com, sol.com's
server might refuse it for too many addressees.
