Thanks Scott, I did read that the way IMail processes mail the messages can be delayed...
They *will* be delayed.
IMail has a certain maximum delivery capacity (that varies depending on many factors). Before that capacity is reached, it will send out E-mail with 100% effectiveness. However, any E-mails that are sent to IMail *while* it is at 100% capacity will be delayed. That's the problem -- IMail v7 and earlier don't handle that delay as well as they could.
If you send out those 7,000 E-mails at a rate less than IMail's maximum capacity, they will be sent out as quickly as you send them to IMail. If you send out those 7,000 E-mails as fast as IMail can accept them, you'll find that probably 6,800+ of them will end up delayed.
but as IMail can typically send several hundred thousand emails a day without assistance...
That's assuming a normal scenario, where E-mail arrives randomly, and doesn't arrive in bursts.
Assuming an IMail server that handles 250,000 E-mails/day with no problem (that's about 3 E-mails/second), if you try to feed it 7,000 E-mails in 5 minutes, that's 23 E-mails/second. So there you are expecting IMail to handle a burst rate of 2,000,000 E-mails/day (8 times what it normally could handle).
i was wondering if there was anything blocks that I can remove to make it more efficient...
Yes. You've been given you at least SIX suggestions in previous posts, that you have been responding to, but don't seem to be able to see the suggestions in. Maybe this list will help:
[1] IMail v8 handles the overload much better
[2] Our free Declude Queue handles the load much better
[3] Have IMail send outgoing mail to a gateway
[4] Have your program send directly, or to a gateway, instead of to IMail
[5] Have your program batch E-mails (such as one E-mail to 20 recipients rather than one E-mail to one recipient)
[6] Have your program send E-mails more slowly
