I have been using the greylist feature for some time (almost from the time it was offered) and I have really appreciated the amount of spam it has removed from my account, but I have just a small complaint.
Usually I don't have an issue with waiting for an e-mail from a new correspondent to be cleared through the greylist, so I just let it work automatically.
Occasionally, I am interested is getting a new address cleared quickly, so I use the greylist management tool in webmail options to find the new message and clear it personally for delivery. When I do that, it disappears from the held list immediately, but doesn't show up in my inbox for up to an hour later.
I would appreciate it if someone would look into why it doesn't show up in my inbox immediately.
