[Dovecot] Question regarding layout.
Hello all. I have a question regarding my mail flow.
We have some users who are in a mail group (alias), and these alias receives a lot of attached documents. So i have the document in all the mailboxes of the alias. If the attached document is 2MB and that is not rare, i have 10 times 2 MB on my mail server. Is there a way to tackle this. Maybe by making the alias a mailbox itself and give other users acces or are there other options.
Also i have very lame and lazy users. They refuse to clean thrash cans (i asked about that earlier,and got that tackled through the expire plugin.),also the do not remove old mail not even reading it. So is there also a option to remove mail that is not been opened, and is older than xx days or weeks.
Thanks

I understand that, if you're using Maildir, Dovecot deliver can be smart and lay down a single file, and hardlink or symlink it to each folder, thus having one physical copy for N users.
The documentation on dovecot's LDA mentions the -p option which will hard-link when using maildir, if possible, specifically for this case.
Also i have very lame and lazy users.
Don't we all, mate? :)

There's expire (http://wiki.dovecot.org/Plugins/Expire) though I'm personally in favor of Quotas -- even if you only go as far as making users request an expanded quota when they reach their limit, it makes them realise how much they're using, AND makes it a chore...
Another thing to look into is the zlib plugin. If you're using mbox, this will allow you to use compressed, read-only folders. If you're using Maildir, it allows you to compress individual messages. http://wiki.dovecot.org/Plugins/Zlib
Someone recently posted a tool to implement something close to the process described at the bottom of that page.

-- Curtis Maloney Thanks for the pointer, but the -p option is not recommended.

thanks for your time.
