For 'administrative' purposes, the postmaster@ address is commonly expanded within the /etc/aliases file (or equivalent). This can work for an abitrarily long list of 'real' recipients. But that *ordinarily leads* to perhaps one to half a dozen actual system admins, one or more of whom are expected to [be able] to take some [corrective] action with alacrity or communiate with another sysadmin about a common issue. This - plus insuring that postmaster@ (optionally abuse@, hostmaster@, webmaster@) are protected but reachable by 'real folks' should be all you need. Ex: Insisting that postmaster@ is a sole addressee of an incoming message can reduce spam on this address. Operating a *general* catch-all OTOH, whether on postmaster@ or *@, is generally a Very Bad Idea, as it opens the door to a spam/malware road *very* well-traveled. Better, IMNSHO, to expect legitimate correspondents to 'get it right' w/r the spelling of a recipient's address - a no-brainer when hitting an MUA's 'Reply' button anyway - and strictly enforce verification so as to accpet traffic ONLY for legitimate recipients. That should not be hard even when your 'customers' are adding and deleting their own mail addresses without your involvement. If Exim can 'see' the mailstore, table, file, or DB entry for one of these users, it can vet their existence. If it cannot, it won't be able to deliver specifically to them anyway, so it SHOULD reject right up front. Some reading up on all this might serve you well...
