SMTP timeout when sending multiple emails

[ishakya]

Hi all,
I have a php page to send multiple emails to different mail id's when user submit a button.but when i submit a button,emails will be send to first 7 or 8 mail id's.i think this is happening because of the timeout.

So hope all got the idea.
help me to figure this out
thanks in advance
