I have configured "sendmail" server with Squirrelmail webmail.

This Mail Server is basically will be used for "Sending Bulk EMails". We have WAN IP with FORWARD,REVERSE & MX Entry.

Now, I have got a huge database of Emails & I tried a demo mail execution from my mail server.

after some hours, i came to know that out of 1000 emails, 200 emails are having wrong characters & that's why they got bounced.

Some of the Bounced Messages is given below.

1) User Mail id is wrong.
2) User Mail Quota Full.
3) User Account Expired.
4) User mail server is in Blacklisted.

So,As i have a million of User Name Database, I need to fetch "wrong mails" ,so that i can delete those mail id's from my mailing list.

Bounced Message will create more problems in my mail sending process.

I am using "phplist" software tool to create a "Mailing List" & "Bulk Mail" sending process.

So, is there any method available to check wrong email id's before sending bulk mails?

Waiting,

1) Try to validate the email domain ( mx lookup )
2) Nope, unless you send him an e-mail and parse the errors
3) See 2)
4) Blacklisted?Aren't you the sender?
