Send mail to multiple address

[Mattia]

I have a very big problem.
I must send a single mail to multiple receivers. The number of
receivers are very big: approximately 6000 users, but this number
increase each year.
I find a lot of suggestion: insert all e-mail address (or part of them)
in the field BCC.
But I use a hosting server, for this reason I don't know if this
solutions is possible.
I can use my computer, but I don't know is SMTP of my ISP can support
this kind of feature.
Anyone did have the same problem? Can I resolve it?
Sorry if my English is not very good.

with

To: yo************* @example.com and not with all recipient names in Bcc:
field (for example I think Sympa - www.sympa.org - is a good mailing lists
server). Why would they do so if there was no reason for it ?

Well, I checked and I am wrong: my address doesn't appear in the To: field
in newsletters I received from Sympa.

Sorry,

SMTP is supposed to support a minimum of 50 addresses for a given

Where did you read that? Wherever it was, I wouldn't trust anything else
that it says. RFC2821 clearly says:

The second step in the procedure is the RCPT command.
RCPT TO:<forward-path> [ SP <rcpt-parameters> ] <CRLF>
...
This step of the procedure can be repeated any number of times.

Perhaps the previous poster is misquoting RFC2821 sec. 4.5.3.1 "Size limits
and minimums":

" recipients buffer
The minimum total number of recipients that must be buffered is
100 recipients. Rejection of messages (for excessive recipients)
with fewer than 100 RCPT commands is a violation of this
specification. The general principle that relaying SMTP servers
MUST NOT, and delivery SMTP servers SHOULD NOT, perform validation
tests on message headers suggests that rejecting a message based
on the total number of recipients shown in header fields is to be
discouraged. A server which imposes a limit on the number of
recipients MUST behave in an orderly fashion, such as to reject
additional addresses over its limit rather than silently
discarding addresses previously accepted. A client that needs to
deliver a message containing over 100 RCPT commands SHOULD be
prepared to transmit in 100-recipient "chunks" if the server
declines to accept more than 100 recipients in a single message."

Each time a mail is correctly sent, I write it in the database.
And I stop as soon as there is an error.
Then I can decide to loop over all the users who I didn't send the mail to
or to loop over them 100 by 100 or 500 by 500.
Each time I run the script it sends the mail only to users who did not
receive it, until there are no more users.

Blob - I also loop through (and in batches) ... but your idea of
flagging an address as "sent/OK" is a good one - many thanks.

Invaluable for those awful early testing stages of a mail-out when you
(embarassingly) send to some users more than once ;-)

Do you mind if I ask where you are hosting that will let you send out that
many emails? I have been looking for a solution for some time....

Thanks,
