I thought the "Greylisting for Qmail" ART packages were only for using greylisting for your own spam filtering (for incoming mail) and Plesk's Qmail implementation already had greylisting support on board for sending mail?!

I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
<xxx@xxx.xx>:
xxx.xxx.xxx.xx does not like recipient.
Remote host said: 450 <xxx@xxx.xx>: Recipient address rejected: Try again later
Giving up on xxx.xxx.xxx.xx.
I'm not going to try again; this message has been in the queue too long.
