Is the boiling point directly related to the volatility of a substance?

[requal]

I know that volatility is more or less proportionally related to vapor pressure.

If they are directly related, are they any exceptions where a more volatile substance may have a higher boiling point than a less volatile substance?

I wonder if volatility is defined precisely enough - as long as it is just a tendency of substance to vaporize (without any numerical/exact approach) sounds like more volatile substances will always have lower boiling points.
