Assuming your A and D strings are intonated correctly, the length of that E looks about right, maybe even a little too far back.
As in the comments, check the neck relief and the action, and get those about right before checking the intonation. Intonation needs strings to be pressed down - I use 12th 19th and 24th fret (if there!) to check. Harmonics will always work, but the strings need to be fretted to check, and if they're high, they stretch out of tune, so intonation is well nigh impossible.
That E looks very low in comparison to the A and D, can't understand why, even with a cambered fingerboard. Check all string heights first.
Since one part of the set-up will affect another, keep checking: neck relief; action/string height; intonation; neck relief; action/string height;, etc. And in between all this, there's the springs on the vibrato to consider...
If you do find that E saddle needs to go back further, and I'm a little sceptical, remove either the spring or some meat off the end of the saddle. Another slight problem may be unusual strings. Heavy gauge will need longer speaking length, but adjustment is available to a good .048"+. I guess before the set up you put new strings on? If not, it's the next move!
