I would also agree there. The big TelCo ISP's are so clueless it's not even funny.
Rather than elaborate a long boring story about more incompetence, I'll just 
nod my head profusely.

Ok, so port:25 blocking still seems to be a bad idea for the mostpart because
ISP's (in general) still do not have their act together. (and looking
at how they spend their money probably never will.)
