More info on BCC? (was Re: [PHP] Sending Broadcast Email - will a large loop cause a crash?)

What's the reasoning behind that number? (330-) I'm about to implement something similar, using BCC (since the emails don't need to be personalized). I've searched in the past for the answers to 2 questions, but haven't had any luck. Can you shed any light on the issue? 1. Is there a limit on the number of BCC recipients that can be included? (Is this where you got the 330 number?) If so, what is it, and if not, what is a reasonable number to include in a single email (1000, 10000, 100000, etc) 2. Is it possible, using BCC from a mail() function in PHP, to accidentally reveal the list of recipients to anyone who receives the email?

Well, try it - find a willing victim and just do a simple loop. Alternately, set up an account with a local, high-bandwidth ISP, batch in groups of 330-, and use BCC. Miles At 04:16 PM 9/6/01 -0700, Fotwun wrote:

Hi, I need to send a broadcast email to our customers (about 3,000 emails). The data is being drawn for the DB, and will be personalized. Obviously, the code to do this is only a few lines. However, I am concerned with the load it will put on the system trying to loop through and mail() 3,000+ times. Because of the overhead I anticipate this will cause the server, I am planning to do it late in the evening.
