It's easy to do with either, actually. Configure amavisd-new to tag
spam with "-spam", and in Postfix:
recipient_delimiter = -
mydestination = example.com [ ... ]
virtual_mailbox_domains = example.net [ ... ]
$ postmap -q u...@example.net maptype:/path/to/virtual_mailbox_maps
example.net/user/
$ postmap -q user-s...@example.net maptype:/path/to/virtual_mailbox_maps
example.net/user/.Spam/
$ cat ~user/.forward-spam
/home/user/Mail/.Spam/
SQL query tricks might be employed to automatically handle the case
of *-s...@example.net queries, if the chosen maptype is SQL. For a
hash: map, simply script the duplication of regular user entries;
also add the -spam case to your new user creation routine.
Note, examples in documentation of both Postfix and amavisd-new show
the use of "+" as recipient_delimiter. For reasons which have been
discussed on this list, the hyphen "-" is probably better in most
cases. Underscore "_" and dot "." are also good choices.
