[Mailman-Users] Traffic with a large list

Assuming an average message size of 10 KB, and an average of 75 e-mails per day,
mailman will be sending out:

0.01 x 75 x 5000 = 3750MB = 3.75 GB per day

(i.e. mail_size_in_MB x mail_per_day x no_of_members)

That works out to 112.5 GB per month.

I suspect your ISP will want to charge you a lot of extra for that kind of
bandwidth usage....
