Problem in email sending program

[bhakti_thakkar]

hi all,
i have a php page in which i have to send some bulk mails (around 18000 - 20000) to the email addresses which are stored in a table. my DB is oracle9i. also i am validating the email addresses. it works fine. some mails are send but after sometime it stops. i get an error as : Error: it were not specified any valid recipients.

:confused:

Please help me.
Thanks in anticipation

Find the location of the error statement in your program and add a statement to echo the fetched email id. You may find the email which is causing this error.

Thanks for your reply but email address is fine. as i printed the email address and checked it. no problems in it, also as soon as i excluded the email address which was causing the problem, it again started sending the mails.

i want to find the cause of rejection of email so that i can be more careful. i want to know if the email address is fine then what is the cause of not sending mails???

Sorry, nothing more to say without seeing your relevant code!

there are few test cases that i am running to see it. as i am finding that it is rejecting sending mail to a specific domain.
reagrding code its scattered in multiple pages
set_time_limit(0);
require("mail/email_message.php");
require("mail/smtp_message.php");
require("mail/smtp.php");
require("mail/sasl.php");
include('include.php');
include('newsletter/nlfunctions.php');


so let me organize it.

till then how will i keep a check on domains which are not allowing to receive mails or how will i handle this rejections???
