To speed things up, you may want to look at the PHPMailer project (http://phpmailer.sourceforge.net/), which provides a class that facilitates sending the same message to multiple recipients, as well as other aspects of e-mailing, like HTML bodies and attachments.
Finally--if you're sending lots of e-mail I recommend you monitor your MTA carefully--Sendmail has a habit of choking on large mailings, whereas learner MTAs like Exim or Qmail seem to do better.
Cheers,

I am writing a script that will query a database table for some statistical information, and then email it (daily, weekly, and monthly) to a list of subscribers. I don't know ahead of time how many persons will be subscribed to receive the info (it could be 20 persons or 2000 or more). Email addresses can be added to or deleted from the subscriber list at any time.
If I am not mistaken, MTAs have a limit on how many recipients can be specified on the To: line of an email message. What is the limit, or does it depend on the MTA you're using (sendmail, qmail, etc), or other factors? If there is such a limit, then what is the best way to send the message to each recipient?
Thank you.
