Bitwarden allows us to use the generator in order to create email aliases using several services (addy.io, Firefox Relay, Simple Login…) (see ✅ Generate disposable e-mail aliases)
In some cases (e.g. addy.io), we can specify the domain name we want to use for forwarding. These kind of settings are not available for all services. For example using Simple Login we have several domain names available, or we can set the alias to forward to different mail adresses, but these settings are not available in the bitwarden interface and the alias is always generated using the default config.
It would be nice if the email alias services have support for choosing the domain name and the mail to forward to, as most of them support these features.
