No... as long as they support plus addressing, you give them your main address - joesm...@example.com - then they will accept anything addressed to joesmith+anyth...@example.com, and reject everything else.
That's still back at square one.. I often see my addresses sold, and since every address is 'accepted', people never get the 'hint' that an address is no longer valid.
So if I sign up for ABCInc, and use evan+abcinc, then see it's been sold and gets spammed, if they actually rejected it, the theory is since it would be rejected, people would get the hint it's not valid.
You said you only had one real address and everything else was aliased to it. Of course, you'd have to give them the CURRENT list of aliases in use, but just don't create any more aliases. Then you'd only have to send them an update when you encounter a service that doesn't let you use a plussed address (rare, but it happens), in which case you'd have to create another regular alias.
Well, the problem is I do. Maybe it's OCD, but I like to track where my address is used and obtained from, hence LDAP :)
