Oops.  That was a little too strong, if the hosting company means 300
messages, not 300 recipients.  You would need to NOT turn on
personalization, or VERP, and you would probably need to turn off the
monthly password reminders.

Given that, you would still run into the answer that no, Mailman doesn't
throttle.  But some other list management software might work.  Go to the
Mailman FAQ (link in the footer to this message) and search for
for more information.

Rather than a whole new hosting company, you may want to look for a separate
host for your list, one that specializes in lists.  You would then need list
mailing addresses like list.example.com rather than example.com, so the
world can direct the mail properly, and the same for the web interface.
Such a hosting company might prefer software other than Mailman, or might
prefer Mailman.
