Here's some of my considerations ;) First of all, for the matter of anti-spam, please do not use the to for more people than, well .. Usually just one actually. Rather use the 'Bcc:' line. If there's no personalized information in the email (you might, for example, want to start with "Good Afternoon John" for a mail to a fella named John), I'd split up the list in chunks of 20 or 50 or smth. Or at least an amount every mailer could handle. Also, you'll probably want to group those chunks by domain. That way your mailersoftware will have to connect to as little different addessas as possible. Just specify your own address as 'To:' of you want to use only BCC. Or even better, specify something like "Undisclosed Recepients <[EMAIL PROTECTED]>" so those mails will just vanish out of existence.
Or you can, as suggested, make one mail for every recepient. Looks more personal anyways. I'm not sure if it increases the speed here also if you give your messages to mail sorted on domain name but I know it won't hurt ;).
