Hi Simon Gray;
The simple requirement you refer to is a function of ALL
popular MTAs. In
the case of a DBMail system both the MTA and MDA have
built-in capability to
do what you want - DBMail does it better!
1) Using DBMAIL:
------------------------------
For small business operations I always create an alias in
DBMail for each
new user called systemnews thedomain.tld and then send
newsletters to user
systemnews. In the case of one larger corporate property I
give accounting
dept an extra alias called finance.news; human resources an
extra alias
called hr.news and so on. We have over 30 newsletter
categories. All I do is
send the pertinent newsletter to one account and DbMail does
a great job of
delivery. For things like employee/HR structures I create
aliases for people
appointed to the "Christmas Committe" or
"Silver Anniversary" committee
etc... you get the picture. I use http://DBMA.ca to add / remove
single/wholesale aliases etc. The newsletter editors,
committee chairman etc
send one newsletter to their assigned 'special' username
and Dbmail
delivers the required copies. *Nice*. DBMail is completely
awesome for this
kind of thing.
(Another way to do this is to add an alias to every account
for a sub-domain
like "newsletter.maindoman.tld") and then use
DBMA with one click of a
button (http://db
ma.ca/screenshots/screenshot19.htm) to add a 'newsletter
alias' for every member of any or all account groups.)
Or..
Using DBMAIL ACLs (much more sophisticated, modern and
polite!!)
You need to understand ACLs. So your users to a small
extent. If you are not
IMAP people, forget this.
Under the _Public_ folder, create a folder called
"News" and give the
'newsletter message' to anybody under that folder. If all
your users are
using Outlook Express, it sucks for shared folders. It works
but it sucks.
Read here to see how to make it (force it) work

tm#acl
This link will also teach you about ACLs.
Or,
2) Using MTA:
---------------------------
Create a virtual table row that sends any mail for somedomain.tld to
*somedomain.tld
The virtualtable is called "virtual" in postfix,
"virtusertable" in sendmail
etc. In sendmail you must rebuild your host.blah.mc to a
host.blah.cf etc.
In Postfix check your main.cf to see how you read your
virtual table. In any
case you *only* change the 'virtual' table and postfix will
catch up. There
is a huge performance penalty on a live production server if
you do "postfix
reload"..
best...

Run a script to output all the email addresses and for each
one send an
email to?
Should be easily handled with a perl or php script (or
whatever your
preferred scripting language is).
Generate the email.
Connect to database, get list of users with an address.
For each user send the email to.
I'd suggest you limit your testing to just you to begin
with, otherwise
you could unintentionally send a bad email out to all your
users (which
I'm sure they wouldn't be very happy with).
