[exim] queue_only

Hi,

I am specifically interested in using the queue_only method to defer
mail until after hours for a particular MTA. I have this working
correctly.

My question is this... will Exim be able to cope with +- 200,000 mails
in it's queue (on average around 3.9 GB for all these mails)
comfortably, or am I likely to run into problems once I restart exim and
the queue runners kick off?

Is anyone else using this, and what kind of volumes are you queueing?

Thanks,
Marc
