Well, there is one other way that I know. I find the codes for the wondermail on Bulbapedia. I just scroll down onto what Pokemon I wanna look up and click on it before scrolling down once again to see the codes.
There is no other one, unfortunetly. If you are writing this question because upokecenter was currently down (which it was) it's now back up!
well i don't know where you actually meet him in a dungeon however i have a wonder mail code for a mission that he joins you after if you want it. To any1 else reading this page this is a Wonder Mail S code not standard wonder mail. Wonder Mail S is for explorers of sky only. just need to point that out -W=TX 6%FX1#6 5K&HY PTJJ+ 1PX+N3% RQH5Y
go to this web site and you can make your own wonder mail codes!!! You can ALMOST do everything on this site for wonder mail. The only thing you cant do is have something to do with legendaries and Pokemon like wiggliytuff, gallade or any one else from team radier, all the big important people in the game. this is the web site. http://www.upokecenter.com/games/dungeon2/guides/wondermail.php Hope this helped. Pika roks :P
Go here, its a code generator. Ive generated a lot of codes myself from here. The only ones that don't work is if you try to modify a challenge. Just about everything else works. :D http://apointlessplace.net/wms/wmgenerate.HTML
Tampering with someone else's mail is a federal offense.

Yes, I wonder.

yes or else it wont mail!
What happens if some else holds your mail and does not return it to the post office
yes
