Re: Default value changes in Cyrus 3

2017-10-19 Thread Stephen Ingram 
I see now that the warning applies to change from altnamespace to not. I
already use the altnamespace, but I want to change to the unix hierarchy
separator where it says the altnamespace doesn't matter. Does that mean it
will keep the same hierarchy?

Re: Default value changes in Cyrus 3

2017-10-19 Thread Bron Gondwana 
Yes, if you change either it will force a re-download of messages and
resync of mailbox listing.
I would recommend setting it to the old values if you upgrade an
existing server.  You can also do something like we did at FastMail -
set up a new hostname with the new defaults using per-service imapd.conf
options, and recommend that  users use the new hostname when setting up
new clients.  That way you don't break things for existing users.
The reason for new defaults in a major version change is to allow new
sites to have sane defaults for the future.

That would be my guess. Have never tried it so can't say for sure.

While we are talking about it, can this just be switched on the fly if
someone is using the "." namespace? Does it only affect the admin in that
you have to type user/mailbox now instead of user.mailbox, or does the
change also affect users?

Re: How to remove attachments from many mails on Cyrus-IMAP Store?

2017-10-19 Thread Bron Gondwana 
Hi Walter,

The only way to remove attachments is to replace the message with an
edited copy of the message.  You can't alter emails in an IMAP mailstore
once they are delivered.
At FastMail we're using the attached Perl module to strip attachments
from emails for our "remove attachments" feature.  It's not pretty, but
it gets the job done.  It needs to be hooked up to some code that
actually connects via IMAP and does the work.
Cheers,

Bron.

Re: Default value changes in Cyrus 3

2017-10-19 Thread Bron Gondwana 
Basically:

1) most of the rest of the world is using '/', so people expect it.
   Also, it means you can use '.' in mailbox names and in usernames,
   both of which people expect to be able to do due to other systems
   allowing it.
2) various clients expect to be able to create top level names and get
   sad if they don't.  The reason not to use altnamespace in the past
   was that it didn't allow subfolders of INBOX, and there were a few
   other broken things about sort.  They have now been fixed, so it's
   safe to make it the default.
Both changes are to make the "out of the box" behaviour closer to what
most people expect.
Cheers,

Bron.

Default value changes in Cyrus 3

2017-10-19 Thread Janos Dohanics 
As I'm preparing to move to Cyrus 3, I have noticed that
unixhierarchysep (/) is now "on" as well as altnamespace is now "on".

I have mostly been using default settings in previous versions, and I
guess one shouldn't change sensible defaults willy-nilly, so I assume
developers had good reasons to change these defaults?

How to remove attachments from many mails on Cyrus-IMAP Store?

2017-10-19 Thread Walter H. via Info-cyrus 
Hello,

my energy supplier sends a daily mail about the electricity power
consumption of the previous day;
these mails have two attachment - one .csv and one .xml

I'd like to remove the .xml attachments from the mails already stored in
the cyrus database, as these are bigger and really not needed;
how would I achieve this?
(how to delete these from each file in the database is not problem)

why I would like to do this:  saving storage ...

the directory has these files:

1.
2.
3.
...
10007.
10008.
cyrus.cache
cyrus.header
cyrus.index
cyrus.squat

my system: CentOS 6, Cyrus v2.3.16-Fedora-RPM-2.3.16-15.el6

Walter
