Hi all,

I'm writing a Java mass emailer application to send out emails to send between 50,000 to 100,000 a day to users.

The current plan is to delegate the sending to delegate to sendmail (on the local unix server).

From our testing sendmail is sending a maximum of 5 emails per second.

Would JavaMail be a faster option?

Does anyone know what a faster way to send emails. We want to get this process out as quick as possible.

Edit: BTW, a pdf will be attached too
