Use async pool when enable async feature

Question

Use async pool when enable async feature

Austaras opened this issue 2 years ago · comments

Currently lettre use r2d2 for pooling but it's a sync pool, when use async it may block worker. Async pool is better when used in a async context. I'd like to work on it if this feature is desirable.

This is not true.
