Allow alias '*' to redirect all email

[David Ventura]

Hi

Some sites do not allow the usage of + in email addresses (they are considered invalid). It'd be great if I could specify that any email[1] should be redirected to another's address:

*: david@mail

[1]: Ideally a * means that any email not matching an existing account (and alias?) gets forwarded, but that is not important for me

Note that such configuration is potentially unsafe for use in public-facing email server. Bots probing addresses will see that all addresses "exist", this might attract a lot of spam or other unwanted messages.

I would use a prefix like david- in this case.

Check suffix_separators option in configuration, you can probably add - there and use it instead of +.

Adding to @foxcpp's answer which I think is spot on.

I use suffix_separators with - to work around the + problem and it has been fairly effective.
You can see the details of that option in the manpage.

If you really really want a catch-all alias, it can be done in a hacky way with alias hooks. I don't recommend it but the possibility is there.

Do these cover your use case?

I think these 2 possibilities are enough to cover what I need, thanks
