i have develped a bulk email sender

the code is read the emailids from the db and shoot a mail

while(dr.read())

{

stremail-dr.getvalue(0).tostring();

msg.to=stremail;

}



this works fine if i send to 1000 max

if i want to send to 5000 at a time

the page shoots sends emails but after some time the page loads back stating page not found.
