I'm sorry, I'm still having  trouble... 
"/usr/local/libexec/dovecot/postfix/deliver -d ${USER}". Command output:

The postfix documentation says the delivery agent is run under the

If I don't specify -d it doesn't access auth-master, so I can
run it without setuid or permissions issues, but will there other
problems?

[Dovecot] FETCH for mailbox mailboxname UID #1 got too little data: #2 vs #3

[Diego Liziero]

I got it with multiple imaptest instances even with current dovecot-1.1 hg tree.

I checked the emails with that UIDs and they are actually truncated.

Some things I noted on these mails:
- they are all with MIME multipart attachments.
- the last multipart attachment is truncated
- the truncated last line is not complete
- the following line is the beginning of a new mail (From line)
without any empty line after the truncated attachment.
- in "got too little data: #2 vs #3"  0 <= #2 < #3 (zero included)
- Content-Length: #4 is sometimes bigger than both #2 and #3, sometimes smaller.

One possibility would be to use dbox format with hashed directories so  
for each mailbox it could create n directories where to store the  
messages. Two problems here though:


1. dbox code hasn't been tested all that much yet in real world (but  
it works well in my stress tests)


2. dbox doesn't yet support directory hashing, but it would be pretty  
easy to implement.

Re: [Dovecot] Dovecot performance on GFS clustered filesystem

[Diego Liziero]

I've read somewhere that one of gfs2 goals was to improve performance
for directory access with many files.

I've tested it doing a simple ls in a directory with many test empty
files in gfs and it was _really_ slow, doing the ls on a gfs2 with the
same amount of emtpy files is actually faster.

But when I tested gfs2 with bonnie++ I got fewer sequential I/O speed
than in gfs (consider that I tested a beta version of gfs2 some months
ago, maybe things are better now).

So my conclusion of the tests was that gfs is best with mbox, gfs2
beta with maildir.

But, again, I haven't tested gfs2 improvements recently.

Regards,
Diego.

[Dovecot] Dovecot performance on GFS clustered filesystem

[Allen Belletti]

Hello All,

We are using Dovecot 1.1.3 to serve IMAP on a pair of clustered Postfix
servers which share a fiber array via the GFS clustered filesystem.
This all works very well for the most part, with the exception that
certain operations are so inefficient on GFS that they generate
significant I/O load and hurt performance.  We are using the Maildir
format on disk.  We're also using Dovecot's deliver from Postfix to
handle local delivery.

As best I can determine, the worst problems occur when certain users
with very large Inboxes (~10k messages) receive new mail and their
client looks up information about that message.  GFS doesn't seem to
efficiently handle the large directories that contain folders like
this.  As a result, lots of I/O ops are generated and performance
suffers for everyone.

I am beginning to wonder if it might be more efficient to revert to the
old mbox format, with one file per folder (plus whatever indices are
creates.)  It seems that this ought to work better with GFS which is
geared toward smaller numbers of larger files.  Is anyone on the list
currently doing that?  Alternately, any thoughts regarding tuning or
other options would be appreciated.

Thanks,
Allen

Yes, indeed.  We (Freie Universität Berlin) published our Cyrus2Dovecot
just a few days ago.  Unlike the older script, ours _does_ try hard to
preserve all available metadata, and this should actually work with all
Cyrus versions (tested with both the oldest and the newest available
Cyrus release, that is, 1.4 and 2.3.12p2, and with various database
formats).  Apart from that, ours provides a few additional features we
needed for our conversion which might also be useful to others, such as
renaming (or moving) folders using s/regex/replacement/ substitutions.

That's what I had in mind. It receives the whole message (including

Actually I agree with the OP.  Thunderbird "works" with attachments, but
it's handling seems very creaky... (I'm a big fan of TB by the way!)

Stuff which annoys me is that it seems to download the attachment every
time it's needed and in particular it seems to download it instantly as
soon as you open a message (OE only downloads the text and gets the
attachment only if you access it - I get a bunch of MB sized attachments

Looks like there are 2 different scripts. If you click the link

But yeah, if the one you referenced above works well, the wiki should be

The wiki page says "cyrus2dovecot doesn't preserve timestamps or flags"
http://wiki.dovecot.org/Migration/Cyrus

However, the cyrus2dovecot home page says:
 "Virtually all available metadata is preserved during the
  conversion. This includes the UID and INTERNALDATE of each message,
  the IMAP folder subscriptions, the UIDVALIDITY and UIDNEXT values for
  each folder, as well as all IMAP flags (i.e., \Recent, \Seen,
  \Answered, \Flagged, \Draft, \Deleted) and the first 26 user-defined
  keywords."

Which to me sounds like the opposite of what the dovecot wiki says.

Perhaps the wiki should be updated?

Been working fine for us on 60+ computers for years, with only one issue
- dragging attachments from the email to the local filesystem

I'd suggest trying first with another client to see if it's not an issue
with Thunderbird, which in my opinion is not very good at handling
attachments in imap.

I used rpmbuild -ba to build the dovecot-1.1.3-0_80.i386.rpm from
dovecot-1.1.3-0_80.src.rpm from atrpms.net. There is also a
dovecot-debuginfo-1.1.3-0_80.i386.rpm in the built i386 directory. Is it
the same to also install it?

Scratch that - appears to have been a Thunderbird issue. Works fine in
Evolution. I'll just use Evolution.

[Dovecot] [Dovecot 1.1.3] Strange problem with attachment download

[Thomas Gropp]

Hello everyone,

I am testing Dovecot 1.1.3 at the moment to see if I can migrate from 
UW-Imap(mbox) to Dovecot(maildir). Because I dont' want to influence the 
production server I installed Dovecot on an ununsed computer with some 
dummy-testusers using ssl and maildir. Installation was without any 
problems and everything works fine with one exception: I cannot download 
some attachments. If the attachment is a simple textfile or bitmap it's 
ok, but everything else (pdf, zip, etc. - size doesn't matter) does not 
work. Here is what happens:


1) I right-click on the attached file -> "save as" (using Thunderbird 2)
2) I choose a target dir (no matter if local disk or nfs)
3) the download-dialog pops up and says: "starting"
4) nothing happens form then on

In the log file I see (lots of them for a single 
"attachment-download-try" until I stop Thunderbird):
"dovecot: Fatal: IMAP(): io_loop_handle_add: epoll_ctl(1, 1): 
File exists" (which file??)


I googled this message but without success. I already tried having all 
files on the local fs instead of nfs but it doesn't change anything. I 
also tried a lot of different settings (concerning locking, nfs, 
permissions) in the dovecot.conf. Everything else works just fine: 
logging in, receiving, creating folders, deleting etc...)


Im using a (very) old SuSE 9.0 installation with ext2.
I put my (current) devecot.conf and the output of "dovecot -n" at the end.

As I have no idea what else to try/check:
Anyone out there who has a tip what else I could check to solve this? Or 
even someone who had the same problem with a solution? ;o)


Thx
Thomas

Re: [Dovecot] One fs with quota, one without: incorrect data shown

I half-expected such an answer :-)
Well, I can't switch to 1.1 right now, but I'm going to start evaluating
it soon.

Still, I'm not sure where the values displayed come from?

The MUA says 5426404 of 1200 KB ni use.

But that doesn't match anything:

/dev/md/dsk/d20269G66G   201G25%/export/home
/dev/md/dsk/d10135G56G78G42%/var/mail

Filesystem usage  quota  limittimeleft  files  quota  limit
timeleft
/export/home 1356601 300 320  0  0  0

I'll give a try to 1.1 ASAP.

[Dovecot] Can't move mail items to Inbox

[Phillip Smith]

Hi all,

Trying to setup Postfix / Dovecot / Fetchmail to collect all my mail
centrally on my home server and serve it out by IMAP. Everything is working,
using Maildir format except I can't move mail from a sub-folder to my Inbox.

Example: I send a test message to myself. It gets picked up by fetchmail,
and delivered to /home/user/Maildir/new by postfix. Dovecot serves that out
to my client. I can then move that message from the Inbox to a subfolder,
but then I can't move it back to the Inbox. I don't get any error messages
or anything - it just doesn't happen :(

Any help and advice would be great.

[Dovecot] authentication issue - dovecot + Mysql

[Reinhard Sanjeet Lal]

Hi,

 

I have a FreeBSD 7.0 server with the following version of software's
installed:

postfix-2.5.4,1   

postfixadmin-2.2.1.1

roundcube-0.2.a,1

php5

mysql-server-5.0.67

dovecot-1.1.3_1

 

Note that pre-reqs for all of the above also has been installed. I have used
this guide to walk myself through the setup :
http://www.purplehat.org/?page_id=4

 

My setup uses virtual domain and user style(mostly for hosting provider
type) , all stored into the Mysql db, now when I try to telnet to port 110
for pop test or even telnet for IMAP test , I get this error:

 

dovecot: Sep 24 18:51:49 Info: pop3-login: Aborted login (auth failed, 1
attempts): user=, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured

 

note : there are numerous of there errors , but I included only this. 

 

Dovecot is not able to authenticate by using the query in its
dovecot-sql.conf file. I have tried a lot of tricks by changing the
mechanism MD5 , PLAIN LOGIN etc, but no avail.

 

Please , could someone assist me in solving this issue, not that I can send
and receive emails but pop and IMAP seems not to work , so is the  webmail
functionality .
