No. Perhaps a few hundred thousand if the turnover isn't that high. Add
and remove operations scale linearly with size. Time to delivery is
almost entirely defined by your MTA at this size.
WRD> What's a mailing like this likely to do to me?
That depends. If you're running bulk_mailer with ten addresses per
envelope, your server will explode into a smouldering blob. Otherwise it
isn't going to do all that much except eat your network bandwidth and take
a while. If the list has a lot of bounces then you will have to deal with
all of those, which could be more problematic than the outbound traffic.
The only time when a large mailing list becomes a problem is when you can't
deliver the mail fast enough, so that you have a permanent and growing
backlog.
Of course, if it's spam you're sending, expect things to explode just
because of hacks, mailbombs, complaints and nice folks setting their MTAs
to sleep for a while, then fail with 4xx error codes (temporary failures)
so you spend all of your time retrying deliveries. It is very difficult to
spam 'legitimately' (i.e. without forging the return address and hijacking
someone else's servers) because people will know where the mail is coming
from and they won't be happy.
