Efficient Way to Deliver A Large Number of Email

[hardi]

Hello,

I have a program that has function to deliver invoice to customer using VB.

I want to improve this program.

My friend's idea is to deliver those invoices trough MS Outlook Express. But, there is a problem. The queueing batch that allowed to enter email server is 256 items/batch.

I have to deliver 18000 email to customers.

Any better idea to accomplish that task?

What are you currently using to deliver the email?

[hardi]

Currently I use MAPI to send each email to Outlook Express.

Email server that we have is using Linux as the operating system.

When this system finished sending all emails, email-items that was sent is not match with number of invoices which have to be sent.

Do you have a better suggestion?

I am not too familiar with using MAPI, but couldn't you queue up all the emails in your program and then send out 250 at a time until they are all sent.

Just an idea.

If your system is NT Server, I would try using CDONTS. It'll run much faster than MAPI. It's also quite simple to use.

Thank you folks, for your bright ideas.

And, dear CompuGEEK, where can I get this software, CDONTS?
