feature request: providing context for Verify function

[yudintsevegor]

Good afternoon.

Current implementation doesn't accept context.Context on function (https://github.com/AfterShip/email-verifier/blob/main/verifier.go#L63):

func (v *Verifier) Verify(email string) (*Result, error) {

that doesn't allow users to cancel the request if it takes too long to execute it.

Underneath net package is used without context (f.e.: mx, err := net.LookupMX(domain) (https://github.com/AfterShip/email-verifier/blob/main/mx.go#L14)). However, net pakcage includes Resolver functionality which accepts context as an argument.

I assume, changing the signature of the function with new input arg ctx context.Context would be a breaking change.

• Do you have an intention to provide v2 of the package with this and any other changes in mind?
• Do you see any blockers to do it in the nearest future?

I guess, I am happy to contribute and provide this feature, but asking in advance if you have any general concerns about it.

Thank you!
