How to increase speed of mail process

Hi
I developed an application to send html emails using Java Mail Package. In that application I am storing all my email addresses in a database. So application reads each email address from data base and sends mail to that address. Application is working good.
But application is taking nearly 30 seconds to send mail to each recipient. Can any body tell me how can I improve speed.
Thanks

Dear sripad
If sending mail is slow its probably due to the connectivity or the smtp mail server perofrmance that you use. If there are only a few address I think you can avoid database storage itself. Maybe you can create a property file.
If the content to all the mail is same you can send to multiple recipients the same mail.

Java Mail service is pretty fast .
try another mail server if u r not getting enough performance. u may use James . Its a pretty nice mail server developed by jakarta . ya the same jakarta that developed Tomcat .
Ur net connection band wirth may also be a bottleneck .
