I think you have a point here - it would make sense to have both options,
actually:

1. Remove the limitation, BUT
2. With an option to "export" a list of email addresses and the message to
a bulk email server when the number of email recipients are above a Systems
Setting specified number.

The main challenge is likely to be security, in the sense that the Dept of
Health will NOT be willing to use a commercial service for this since it
would give such a service access to all the emails for specific groups like
all health graduates or all health staff (which they might misuse or sell
to other companies doing marketing).

So we need to identify either a piece of open source software that can be
incorporated into DHIS2 or at least run in parallel with DHIS2 - both will
take a list of emails and a message and then bulk mail them out. I see
sourceforge have a bunch of FOSS email senders, but not sure which is best
(if any). Could be a commercial variety too, of course - I would not expect
high cost.

Regards
Calle
