Mailman doesn't do this.

You can set SMTP_MAX_RCPTS = 250 in mm_cfg.py to make sure that no
single SMTP transaction sends to more than 250 recipients, but Mailman
will still send to all 750 members with as little delay as possible.

It would be possible to modify Mailman/Handlers/SMTPDirect.py to keep
track and not send to more than 250 recipients per hour, but that
might result in large backlogs.

Anyway, would this be your Mailman installation or the host's? If it's
the host's, there's nothing you can do and what they seem to be
telling you is they won't support lists with more than 250 members or
more than 250 (posts X members) per hour.
