do that in dovecot.

what is a "user"?
if you insist on doing this in postfix, then
1) use virtual_alias_maps to convert the address to
someuser@fixeddomain.example.
2) in the pipe that defines dovecot, use -d ${user}
but note:
- this removes the domain part, so you must make sure all users map to a
different user in the fixeddomain.example
- this doesn't pass the '+' extension. so you can't use this feature in
dovecot (storing extension mail in subfolders).
you've been warned.
> Is that a configuration in Postfix?
when delivering with "virtual", virtual_uid_maps and virtual_gid_maps
yield the uid and gid of the mailbox. but that's when postfix delivers
mail. not if using an external MDA or relaying mail to another server.
