Case sensitivity in automatic folder filtering by tag

2015-03-28 Thread Kevin Chadwick
If the filesystem supports case sensitivity then I can understand users
expecting the current behaviour but it doesn't seem practical to me and
I couldn't see a format specifier to lowercase deliveries to Maildir
expanding to just TAG.

When someone sends to a tag user+...@users.org and there is an existing
folder Tag then it works great and I really love it, however I am sure
I cannot always trust senders to keep the case correct.

Am I missing a configuration tweak?

Or

Should traditional after delivery filters be used in this case or is a
patch needed for a caseless folder search to be done and using closest
match in case of multiple folders?

Thanks,
Kc

I use the lowercase delivery option to address this issue.

accept from  deliver to maildir  
"/var/vmaildir/%{dest.domain:lowercase}/%{dest.user:lowercase|strip}/mail/"

I was using %{user.username:lowercase} which seems to deliver to the
exact same place as %{dest.user:lowercase|strip}

As far as I can tell so far, this has no bearing on lower casing the
TAG? (portion after the + and before the @).

%{rcpt:lowercase} could work but would break my dovecot config that
relies on the username and would create uglier directories too.

I guess there isn't a tweak currently and so should decide if I have
time for a patch, the filter api or simply traditional client filtering
as I had to use with qmail anyway.

Doh!, when I did that test I was editing the from any rule and sending
from local. I thought it was strange that it did the same thing.

So... Ace, this feature can work this way but you need a dot in
front of the folder for IMAP client compatibility and I'll have to find
a way to automatically check for new folders regularly or on client
startup.

/%{user.username}/.%{dest.user:lowercase}"

Still trying to decide if it's worse but leaning to actually better?
than a patch or filter which only delivers if the directory already
exists (still creates both) and may save me the time I haven't got,

Thanks.
