I've just re-opened an old account that I haven't used for a many years. I'm on the new MP system, so that's all fine.

I know that funds are held for 21+ days until delivery is confirmed, but could someone advise if do they do this for the first x number of transactions, or x number of months? Is there a benchmark figure whereby these limits fall away or is it arbitrary?

Items will still be posted, but I'm just trying to get an idea of what cash flow issues are going to be like for the next while.
