Hi, I regularly use PHPMailer to send out a mailshot to two batches of 50000 and had no problems at all. I would not use BCC. Just set the recipient, send the email, then use the ClearAllRecipients() function and start again. We do other things like set a custom MessageID for tracking bounces and auto unsubscribing during this process as well. I also do this from the command line so I don't have to worry about timeouts / apache memory issues etc. But as long as you're aware of these problems then you can set the values appropriately.
