qmail does this by default. Each user may have extension addresses.

Assume your email address is: user@domain.tld

You may then supply an address such as: user-newsletter@domain.tld

Delivery instructions are controlled by .qmail-newsletter in the same
directory as that user's .qmail file. You may then specify a
..qmail-default in that user's homedir to catch all extension addresses.
I use this feature myself to tag addresses just as you mention below.

Read `man dot-qmail` for details.

No "dashboard" required. If you are using POP3 for users, there is
generally only one mailbox to deliver to anyhow. symlink .qmail-default
to .qmail and you are done.
