Yes, very true. Actually on shared servers, most ISP would not allow you
to send messages to that many recipients even if you use just send one
message in Bcc for all because in the end it will consume much bandwidth.
Some people think that working around the problem by sending just to a
few hundred at a time will solve the problem, but they are just fooling
themselves because it will still consume the same, if not more, bandwidth.
Another problem why shared server hosting companies forbid bulk-mailing
is that they can't be sure if what people is sending is really solicited
e-mail, even if you sware that it is. There is always the risk of having
their IP ranges blacklisted by anti-spammers and they do not want to
deal with that.
Many people are resorting to ADSL/cable lines for bulk-mail (solicited
or not). Because of that, many ISP have included the IPs of those
connection in the Dial-Up List which is basically used by many mail
server administrators to refuse messages as they may be from hit-and-run
spammers.
If you are really sending solicited e-mail, eitheir you use a server
that you absolutely control or hire e-mail delivery hosting services
that are meant for that purpose, despit they currently are not very cheap.
