Wildcard virtual domains for catch-all addresses.

[dequbed]

Is your feature request related to a problem? Please describe.

I'm currently looking at what vSMTP would need to provide for us to be able to switch over to it.

Describe the solution you'd like

We're currently using the PCRE-"database" of postfix to implement ad-hoc catch-all domains. i.e. every user in our network can have mail sent to <arbitrary string>@<username>.<domain>.<tld>, as sub-addresses using "+" aren't accepted by all forms.

Describe alternatives you've considered

¯\_(ツ)_/¯
