Repeated Folder Names

Hi,

I'm seeing an odd issue with the IMAP folders. If I have multiple
sub-folders, When I check folders on a higher level, I see the higher level
folder multiple times, once per subfolder.

For example, if I have I the following folders:

Mail/foo
Mail/bar
Mail/baz

I'll see the Mail folder listed 3 times at the top level, and foo|bar|baz
listed under each of those. Moving mail to/from any of those affects the
same directory on all levels, so it does look like they are actually the
same directories.

This is how things show up in Alpine, and it would also explain why
checking IMAP mail from a Windows Mobile IMAP client takes a very long time
(and several megabytes!) since the number of folder increases
exponentially. Thunderbird on a LAN doesn't seem affected - it only shows
the folders once, but I don't know if it suffers the folder download volume
explosion since that happens at LAN speeds.

Is this a DBmail misconfiguration? Or corruption in my mail database? Is
there anything that can be done about this?

Thanks.

Gordan

this is a known dbmail bug in 2.2, fixed already in 2.3.

But since no of my dbmail-2.2 users complain, there's not much incentive
for me to fix this...

Re: Repeated Folder Names [In reply to]

Ah, OK. Thanks. What is the database format compatibility situation between
2.2 and 2.3? If I upgrade the package, will it all still "just work"? Or is
there a more involved migration procedure required, involving modifications
or dump/restore of the database?

Thanks.

I just tried building 2.3 on RHEL5, and it rapidly turns into dependency
hell because of gmime version requirement inflation. Is there a patch for
this that went into 2.3 that could be thumped a bit to fit 2.2? This issue
is particularly crippling for mobile users because it makes their IMAP sync
megabytes rather than kilobytes in size. Alternatively, is there an older
version of 2.2 that doesn't suffer from this issue?

Thanks.

Re: Repeated Folder Names [In reply to]

There is a sql migration from 2.2 to 2.3 that needs to be done in
addition to dbmail-util runs. This could take longer than you expect to
do. I'm not sure what the response difference is between 2.2 and 2.3
that needs to be corrected. Perhaps I'll test it later to see what I get.

Re: Repeated Folder Names [In reply to]

I think 2.2.10 does not seem to suffer from it.

As I tried to downgrade earlier I got into problems with strtoul.

Marc

So 2.2.10 works but 2.2.11 doesn't?

Re: Repeated Folder Names [In reply to]

I started seeing this regression after upgrading to 2.2.11 from 2.2.10 yes.

2.2.10 has other bugs which are solved in 2.2.11.

I just rolled back to 2.2.9 and the problem disappeared. Yet another
upgrade exclusion in my yum.conf. Thanks to those of you who pointed out
that the bug was introduced in 2.2.11.
