Hi
Yes an open source application/api which deals with thousands of emails. JAVAMail is using single pool/queue to send email. I need a multi-threaded application which can send emails using multiple pools for minimizing load and time.

you can spawn threads to send an email parallelly!

[Farrukh Jalil]

OK - but all the thread use same message queue for they have their separated message queue?

If each has its own queue then my problem will be solve.... what you say?

Got an open source enterprise email server Apache James, but I have a question regarding the email server

"Can we add custom fields in database tables (spool/inbox) and insert or update the tables using james when an email shoot?"

I need to create "email log" for bulk emails with particular event in our portal.



What you suggest?

Hi Farrukh,

I don;t know about Apache James, but you can accomplish the same using Java Mail API.
1.Create a table with data structure TO,From,Subject,Body,Attachment,WhenSent,etc..(i.e as columns).
2.For every email to be sent, insert those values into MailLog table.
3.Later run a Java program (say for every 2mins) which loops through each unsent mail and fires a email using mail API and updates the whensent column once delivered(you can also think of MultiThreaded coding here for better efficiency).


Thanks

Hi Arun,

Your idea is superb, I will try it out using Java Mail API, but here one thing comes in my mind that
will the said API support arround 15,000 bulk emails?

Thanks for the reply,

The solution comes with Apache James enterprise email server in which spooling repositery maintains for every email. but I need to customize the database repositery i.e. the table with my columns like EventID, EmailJobID etc. That's why, I was asking about apache james. my last option is to use java mail API because I have to do lots of work for multi-threaded email sending mechanism with logging.

Nice to see the reply guys. Its very helpful to discuss issues in a friendly environmnent.
