It is remarkably reliable considering.

And all the more dangerous for it.

"Unreliable" means that unless you build up some proprietary layers
around it, you can't guarantee a sent email has been received.

See also: SMS

That does not make it unreliable.
Back in the day when we were putting it up against X400, the standard
FUD from the big boys was 'but you get no guarantee of receipt'
I said 'but it gets through ten times more often'

Dropping mail silently contravenes the protocol. But it is exactly what
big mail servers and spam filters do
