I recently finished migrating users to an Ubuntu server with a fresh install of Virtualmin and Ubuntu 8.04.
A user fired up Usermin, and proceeded to add a number of filters, using the "Filter and Forward Mail" module.
It created a number of entries similar to this:
* From: .*godaddy.com
$HOME/Maildir/.Hosting.godaddy
What that ended up doing is dumping all the emails into $HOME/Maildir/.Hosting.godaddy though -- not Maildir/.Hosting.godaddy/new!
Dovecot doesn't look for them where it was putting them.
After looking up the syntax in how the spam filter works, the spam filter adds a trailing slash:
$HOME/Maildir/.spam/
I manually added a trailing slash to the various filters he had created, and that resolved it.
But is there an option in there somewhere that I need to tweak such that filters he creates in the future add that slash automatically?
