Yes, but they'll still support 32on64, no?

Thank you, I updated the documentaion.

Thing is, a 64bit binary will use a lot more memory than a 32bit one, 
mainly because all pointers are double the size. If an application does 
not need a VM space bigger than 2GB (and XMail doesn't, unless you're 
handling yahoo.com with a singel machine), it's better off using a 32bit 
binary.
I will try to look into building a 64bit eventually ...
