Build a native function that allows sending Emails from Bun

[truongan07]

I understand Bun's talented team has so many functions in development but I hope the Bun team builds a native function that allows sending Emails from Bun. This will make Bun become popular where businesses in the field of Email marketing will use Bun as their Email server. E-commerce platforms will want to switch to Bun for their systems.
