How could I increase my server's Message sending limit at one time?

[highopes]

Please anyone tell me about how can I increase my server's msg sending limit??
Is there any alternate method to increase msg sending limit at one go??
I want to import email addresses form mail providers like gmail etc and want to send invitation mail to all the selected contacts which can be more than 1000...

Please help me... I got stuck in this unwanted situation....

You need to speak to your hosting company as they set the limit on SMTP traffic and will tell you if and how this can be increased.

I will tell you though that unless you are on a dedicated server then usually these limits are hard to get increased.

If your host is IPS, then open up a ticket in your client area.
