Cargo Features

mail-auth = { version = "0.4.2", default-features = false, features = ["rust-crypto", "generate", "test", "ring", "rustls-pemfile"] }
default = ring, rustls-pemfile

These default features are set whenever mail-auth is added without default-features = false somewhere in the dependency tree.

rust-crypto = ed25519-dalek, rsa, sha1, sha2
generate = rand, rsa

Affects dkim::generate


Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
