dovecot - Oct 2014 - Fwd: Re: Wiki advice on running getmail on INBOX access - how does that work?

Just re-tried this, and it doesn't seem to fire getmail on access for me.

My incrontab is as follows:

/home/user/Maildir/cur/ IN_ALL_EVENTS,IN_ONESHOT /home/user/bin/mvmail.sh

The incrontab rule does work, but only if I make a physical change in
/home/user/Maildir/cur/ e.g. by moving a mail from another folder in
there.  Just accessing the particular inbox doesn't seem to trigger
anything.

In my testing I get 3 events every single time I list the test 
directory, if I remove the IN_ONESHOT.
With IN_ONESHOT, I get only one, for the first time.
The script on the wiki ends with:
incrontab --reload # Rearm the one-shot rule
So that makes sense.

Debian Jessie, Linux 3.16.5-1 amd64, incron 0.5.10-2
