dovecot - Jul 2012 - getting rid of old spam from +spam Maildir ?

I'm trying to setup per user '+spam' delivery from amavis tags, so
that
each user gets any mails tagged as spam to 'spam' Maildir via +spam
Dovecot lmtp delivery.

after say 7 days I want to delete all spams older than 7 days,
if I simply delete mail files from the file system, is that a 'bad
thing' ?

what is a proper way to do that, and scripts ?

for removing/archiving old uncollected emails in main INBOX I use
archivemail from sf, but, don't think I can do subfoldrs with archivemail

any pointers (and scripts) welcomed, thanks

i have no amavis, i use a global sieve rule to deliver tagged mail into
special Junk folder, and virtual plugin to get users the chance to
download tagged mails from Junk folder via pop3 too

look i.e here

perhaps use daily cron with something like this

doveadm expunge -A mailbox Junk  savedbefore 7d;

i don't use lmtp so maybe i'm wrong but if you use maildir format just 
deleting/moving files always work properly

IMHO 7 days is dangerously too short. False positives during vacations
happen too ;-)

I would suggest at least 30 days (as used by Gmail).

where am I going wrong ?

nothing gets removed:

Perhaps this related thread starting at
