[AMaViS-user] delivering spam to individual users with + subaddress and virtual mailbox

[Voytek E. <li...@sb...>]

I have postfixadmin 2.2.0, amavisd-new-2.6.4 (20090625), ClamAV, bdc,
CourierIMAP, virtual domains/users in MySQL, it all works well, thanks.

currently, all users spam goes to 'all_users_spam' mailbox.

I'd like to implement '+' subaddressing for user+spam.

reading a thread on postfix list, I realized that postfix's virtual
delivery agent supports '+' subaddressing

so, using postfixadmin, I added a new mailbox 'voytek+spam@...', then,
edited path in SQL field to point to 'vo...@do...d/.spam/'

that seems to work OK, if I send an external email to
'voy...@do...d' it ends up in 'spam' subfolder of vo...@do...d,
using Postfix's virtual delivery agent

so, I'm thinking of adding to all users a 'user+spam@...' 'mailbox', with
a Maildir path edited to end in 'user@.../.spam/'

is there any problems doing it like that ? anyone uses something like it ?

I already have delimiter set
# grep delimiter amavisd.conf
$recipient_delimiter = '+';  # undef disables address extensions altogether

so, once I remove my current
$spam_quarantine_to = 'all...@do...d';

then all spam should be delivered to each user
those that have 'user+spam' virtual mailbox defined and setup, will get
that delivered to spam folder
those that do not have 'user+spam' virtual mailbox, spam will end up in
main inbox with amavis's 'spam' header

am I correct ?
