Mail queue gets cloaked up

I got the following problem:

I have a mass mailing script (no spam stuff) that is supposed to send out large volumes of E-Mail.
The script is even server friendly by only handing over 100 mails per minute to exim.

What always happens is:
Once I launch a mailing (about 500 E-Mails) a small portion is delivered (20-30) and then the rest gets stuck in the Mail queue. I can see the mails in the WHM. They stay there for at least 30 minutes - some E-Mails a lot longer like 70 minutes. But after a while they are all sent.

If I use the "Attempt to deliver all messages in the Queue" Link on the Mail Queue Screen the mails get delivered immediatly.

Any suggestions what might be the cause for this massive delay? Any way to speed up the process?

Based on my experiences with other mailer daemons, I'd guess that exim is set to only handle 30 or so messages at a time, and spool excess.
AND,
the default queue runner job probably is running less often than every 30 minutes.

Easiest fixes:
increase the max exim threads
and/or
make the queue runner run more often.

I'm not familar with exim, but I'm sure there are settings for these things.
