The right wording (expunge) provided me with some clues. Anyway, Mac Mail does not have such a flag. It seems to be deliberately designed to do the expunge on quitting the application. Expunge can also be triggered by using cmd+shift+k with no marked messages to empty all trashes. Using this command, one can also mark a message and expunge it directly, bypassing the trash.
I don't want to exclude the possiblity that this has got something to do with the IDLE system, and could be resolved by, for example, providing the right IMAP capabilities flags upon com init. Interestingly, iOS mail does delete the message in the inbox directly when moving it to trash. Thanks anyway to the contributors of this thread, I think I will have to accept this behavior, since Apple does usually not care about customer requests to resolve bugs. Mostly they declare them to be intended stupidity, even when they sell items that behave just the opposite way. Anyway, Zarafa mail server has a flag imap_expunge_on_delete. Perhaps this would be a useful feature for Dovecot to protect admins from angry customers who use well-designed Apple products.
