Hi,
Apologies in advance if this is the wrong list, but I wanted to confirm
that what I have done is safe (and sensible).
I want to be able to automatically add keywords to incoming mail from
procmail, so I added a recipe, and a helper script, which I've included
below.
This seems to work really well, however, I wanted to confirm that it is
sane:
1) Is this concurrent-safe? Is there a race if the MUA sees the mail and
causes courier to move it from 'new' to 'cur' while the labelling is
happening? Or does maildirkw cope with this safely?
2) I have IMAP_USELOCKS set to 1 in /etc/courier/imap. Do I need to do
anything with my procmail recipes to make them use this locking too, or
is this not necessary (I read elsewhere that maildir doesn't use locks at
all, so I was a little confused).
3) Can you see any other problems with my approach below?
Many thanks in advance, and best wishes
Matt.
procmailrc:
## Labelling inbox stuff
:0
* <insert reg-exp here>
{
:0
{ TRAP='/home/matt/bin/addlabel.sh \$Label5' }
}
<let mail fall into default folder>
The script, addlabel.sh looks like this:
#!/bin/bash
if [ "$1" == "" ] ; then
echo "No keyword supplied!"
exit 1
fi
folder=`dirname $LASTFOLDER`
folder=`dirname $folder`
msg=`basename $LASTFOLDER`
echo folder=$folder
echo msg=$msg
maildirkw -l -a $folder $msg $1
