When it says "You create only a single namespace", it means you would
create a single extra namespace for the lazy expunge plugin (instead of
 creating *three* new namespaces just for the plugin, as in the later
example on that page).

This extra single lazy expunge namespace would be in addition to any
normal namespaces you already have.

No. Do not touch your existing namespaces at all. You add a new one for
lazy expunge.

Haven't tried that, but perhaps you could experiment with adding it to
mail_plugins in only the "protocol pop3" section, like:

protocol pop3 {
  mail_plugins = $mail_plugins lazy_expunge
}

First all, that shows two namespace sections. Second, my namespace looks quite 
different (maybe it’s from older config version, I am not on 2.3 yet). I have a 
few users with shell access and mail in ~/Maildir but most users are in mysql.

user_query = select 89 as uid, 89 as gid, concat('/usr/local/virtual/', 
maildir) as home FROM mailbox where username = '%u'


namespace inbox {
  inbox = yes
  location =
  mailbox Drafts {
special_use = \Drafts
  }
  mailbox Junk {
auto = subscribe
special_use = \Junk
  }
  mailbox Sent {
special_use = \Sent
  }
  mailbox Trash {
special_use = \Trash
  }
  mailbox Archive {
auto = subscribe
special_use = \Archive
  }
  prefix = 
}

Am I just adding the new namespace for lazy_expunge inside that? And since the 
readme also says to put lazy_expunge and all in the mailplugins line, why is 
this repeated here? Won’t this override the previous setting?

And, finally, is there any way to limit this to only POP3 delete instead of all 
IMAP?

No, but it is only needed for the times someone access the account via POP3 
without “leave on server".

From a data flow (and privacy protection) POV, that wouldn't be much
different anymore from having *the MTA* feed a copy of (all incoming)
e-mails directly into an archiving mechanism, would it?

We do exactly this using the "Lazy Expunge" plugin:

 https://wiki.dovecot.org/Plugins/Lazyexpunge

Despite the IMAP-sounding "expunge" in the name, it works for all
deletions, including POP3.

Now that I think about it, even better would be a way to move the messages into 
an archive box when they are downloaded, this way they will be entirely 
invisible from the POP3 access, and I can use normal expiry functions to clean 
out that archive after backup.

Overrideing pop delete?

2018-12-14 Thread @lbutlr
Is it possible to override the POP3 delete on download command and make sure 
that messages stay on the server for at least X hours or X days?

It is important that the messages be around long enough to hit a snapshot cycle 
(using rsnapshot to backup ever hour).
