500 error in sending bulk mail

Hi All i started a project one year before…form this notifications and mails used to be send… when the mail list was small every thing was working good now my email list increases …in thousands so this 500 error occurs due to the response back time is more during sending mail

to sending mails i used Action mailer and privet SMTP server(which has unlimited capacity to send mail) now i want to manage all these things and some control on sending mails … like which is delivered ? which is pending ?

and which is opened by user.? basically a Email manager … So Please suggest me if any one has idea…

I Google for it and find some applications like http://postageapp.com/

which provide mass mailing … but they has own limitations…

Delivering a lot of email can be difficult, and the big providers don't always make it easier. Yahoo is notorious for rate-limiting incoming mail.

If you still want to deliver mail with your server, make sure the following are set up:

- correct reverse DNS for the mail server

- SPF record for the mail server

- if at all possible, DKIM sign all outgoing mail and set up the DKIM info in DNS

- get onto the various providers' (AOL, Yahoo and Hotmail) abuse notification systems. Sometimes referred to as "feedback loops", these will allow you to receive spam complaints and deal with them correctly. Apparently, rate-limiting is less of a problem if you've got these set up.

You may also want to look into a service like AuthSMTP, which can handle some of the details for you.
