texte = I have a messaging system. It tracks when people open emails, but I did not finish developing the bounce back feature. I'm not necessarily offering my system to you, just some input. To track bounce backs you need to send from a POP3 address and have the messaging system POP that account and analyze the emails received. Here's my issue on why I haven't completed this. I currently have my WebDNA server set to deliver 10 emails a minute, which is 600 emails an hour. But that takes FOREVER to send out large lists. Has anyone here ever set the number of emails per minute to greater than 10? I've never tempted fate since the docs say something like "do do that unless your email server can handle it". Is that a warning from 10+ years ago when we had Intel 486 chips? As for the [spawn] I recently learned that [spawn] has a processing limitation. I created a script to parse through imported database records and import them into another database. The script dies whenever it processes more than 900 records. It took forever for me to figure out that the [spawn] routine was dying. I tried to figure out why by creating internal debug routines for the [spawn] but I was not able to figure out the exact cause. I assume it's a memory overflow or limitation of variables. Therefore, depending on the number of emails sent I would recommend creating an appropriate number of [spawn]s to complete this task. I can also tell you from personal experience that none of the EMailFolders like more than 2000 files at a time. The server or sandbox chokes to death! In my early attempts with this I tried process too many [sendmails] at a time and the server got caught in an endless loop of sending a single email over and over until I rebooted. I wrote a trigger that reorganizes the EMailFolders every night. It moves the done emails into another subfolder and prevents the choking I mentioned above. But if you want to send 400000 emails in a day you need to account for this issue.
