Bulk mail with PHPMailer?

[coldfission]

Is it safe to use PHPMailer to send bulk mail? If so, how do i know it will not time out?

Should i be using the phpMassMailer class? How do i know that that one will not time out?

 

I am using my localhost godaddy dedicated SMTP server to send out mail, and only a couple will go through at a time. I have to wait about an hour for the rest to send. Is there another SMTP server i should be using?

 

thanks
