Re: [Dovecot-news] Released Pigeonhole v0.4.7.rc2 for Dovecot v2.2.16

[Wouter de Geus]

Hej folks,

Today I upgraded from Dovecot 2.2.15 to 2.2.16 and while I was at it also went 
from pigeonhole 0.4.5 to 0.4.7-rc2.
After upgrading I started getting these errors in the dovecot-deliver-error log:
=
lda(t...@domain.nl): Error: sieve: file storage: Failed to normalize active 
script directory (path=/home/vpopmail/domains/domain.nl/test/.sieve): No such 
file or directory
lda(t...@domain.nl): Error: sieve: Failed to access user storage (temporary 
failure)
=

Is this due to a configuration change or is this a bug?
Above problem is as it says due to the missing .sieve directory (not all my 
users have them), but it worked fine in 0.4.5 without those directories.

Thanks,

Wouter.

Re: [Dovecot] Maildir filename has wrong S value

  My question here is: Why does dovecot abort? Isn't the issue fixed after 
  the rename?
 
 That file was fixed, but you probably have tons of them and it aborts
 after each one. With IMAP protocol there's really no other good way to
 do this. I guess if it notices one file being wrong it could just decide
 to go into error recovery check and read through all of the maildir
 files, but that's annoying extra piece of code for something that
 shouldn't happen anyway..

Ah, good point on the protocol. However, as far as I'm concerned this automatic
recovery would be a good thing (under the self healing statement from the 
dovecot site?)
Just a suggestion though, I understand that it's a lot of work for this 
specific issue.

 You should be able to manually fix them by reading them via doveadm,
 something like:
 
 doveadm fetch -u benv text all  /dev/null

Thanks for that one, worked great for my maildir. (and saved me from writing a 
shell script) :)

 Old Dovecot versions didn't notice the problem. You can make v2.1 also
 just ignore the wrong sizes with maildir_broken_filename_sizes=yes.

Ah, that explains.

Well, thanks for the support :)

Regards,

Wouter.

[Dovecot] Maildir filename has wrong S value

[Wouter de Geus]

Hello folks,

This morning I tried to open an old archive mail folder using Mutt.
However, while fetching headers it aborted.
Checking the dovecot log gave me this:

@40004fb21996267d37d4 imap(benv): Error: Cached message size smaller than 
expected (9115  9420)

I've retried opening this folder several times, but each time Dovecot only 
fixes 1 file and then aborts.
(the folder apparently has a lot more files with incorrect sizes).
My question here is: Why does dovecot abort? Isn't the issue fixed after the 
rename?

Also: The files are not corrupted or unreadable, reading them through the 
commandline works fine.
I've looked through my backups and saw that at least half a year ago this 
mismatch in size was already present.

I've been running dovecot for quite a while, so the cause of this size mismatch 
might very well be a issue in an older version of dovecot / my configuration.
Right now I'm running dovecot 2.1.6, but I've been running the v1.2 version for 
quite a while before that.

Is this something that can be improved in dovecot so it doesn't abort after 1 
rename?
(of course I could script a rename operation, but that seems like a workaround 
to me)

Thanks for reading.

Wouter.
