The messages in question are accepted by the Postfix smtpd process and processed by Postfix, and handed off to dovecot deliver. I am not specifying an F flag anywhere.

You're correct; the line prior to the "Content-Length:" header was indeed an "X-Keywords:" header padded out to exactly 80 characters, making it appear that there was an extra blank line after it (my xterm window is set to 80 columns). -- Steven F.

[Dovecot] which e-mail client can work with recent dovecot?
by Sergey Ivanov 09 Oct '06

09 Oct '06

Hi, I'm trying to use dovecot-1.0.rc7. Before I've used dovecot-1.0 from nightly cvs build of August 08, 2006. It worked perfectly, on Linux 64-bit, you can see spec and patches at http://www.sisyphus.ru/srpm/dovecot/ When I tried to upgrade to rc7 and to recent nightly cvs builds with the same configuration and patches (provided necessary adaptations), it builds O.K, but can not move messages from folder to folder. I've tried the following mail clients: thunderbird-1.5.0.7, evolution-2.0.2, sylpheed-claws-2.0 and KMail-1.7.1 (all from Centos-4.4). KMail refuses to copy (or to move) multiple selected messages, saying:" Error while copying messages.Connection to Server Closed Unexpectedly ...". Evolution is not able to open folders at 3-rd level (like dovecot/2006/09), or it is so slow that I was not able to test moving/copying messages in it. Sylpheed-claws died whan I tried this message copying. Thunderbird tries to move infinetly in a loop, filling the dovecot's log with lines: --- Sep 28 12:56:25 alt64 dovecot: imap-login: Login: user=<seriv>, method=plain, rip=66.80.117.2, lip=192.168.10.8, TLS Sep 28 12:56:25 alt64 dovecot: IMAP(seriv): file mail-cache-transaction.c: line 709 (mail_cache_add): assertion failed: (fixed_size == (unsigned int)-1 || fixed_size == data_size) Sep 28 12:56:25 alt64 dovecot: child 25177 (imap) killed with signal 6 Sep 28 12:56:25 alt64 dovecot: imap-login: Login: user=<seriv>, method=plain, rip=66.80.117.2, lip=192.168.10.8, TLS Sep 28 12:56:25 alt64 dovecot: IMAP(seriv): file mail-cache-transaction.c: line 709 (mail_cache_add): assertion failed: (fixed_size == (unsigned int)-1 || fixed_size == data_size) Sep 28 12:56:25 alt64 dovecot: child 25183 (imap) killed with signal 6 --- (approximitely 2 cicles per second). And when I reinstalled back the previously worked version of dovecot, the problem remains. -- With best regards, Sergey Ivanov.

[Dovecot] 1.0rc8 - not quite yet
by Timo Sirainen 09 Oct '06

09 Oct '06

OK, I know I promised rc8 today in my recent mails, but it's way too late and writing changes to NEWS file takes time. :) So I guess it'll happen tomorrow then. In the mean time it would be nice if you'd test that I didn't break anything badly with my recent changes. Especially when I changed the password verifications to detect if the password is in hex or base64 encoding based on the string length. This also allowed me to make LDAP-MD5 and PLAIN-MD5 use the same password verification function. I like this change. :) So, the almost-rc8 snapshot is in: http://dovecot.org/nightly/dovecot-latest.tar.gz I also started building dovecot-sieve snapshots: http://dovecot.org/nightly/sieve/

[Dovecot] Maildir++ quota inconsistency
by Anand Buddhdev 09 Oct '06

09 Oct '06

I've found what I think is an inconsistency in the Maildir quota implementation. According to the Maildir++ quota specification at: http://www.inter7.com/courierimap/README.maildirquota.html Maildir++ quota can be specified as maximum size, or maximum number of messages, or even both. The size specification is supposed to be in bytes. So I could use '10000000S' to set a quota of around 10MB. Now, the Exim MTA has an independent Maildir++ quota implementation, and it follows the specification, so if I set the quota in Exim to 10000000, it will work perfectly with sqwebmail and courier-imap. However, it doesn't play well with Dovecot, because Dovecot chooses to interpret the quota as kilobytes, rather than bytes. An example: If I set the quota to 10240 in Dovecot, it creates a maildirsize file with the value 10240000 in it. If I then set the quota to 10M in Exim, Exim calculates that as 10485760. It detects that the value in the maildirsize file is wrong, and recreates the file with a quota of 10485760 bytes. Exim's behaviour is consistent with the courier family of packages, as well as the specification, so I'm venturing to say that Dovecot's implementation is slightly non-standard, and should be fixed so that the quota setting is interpreted as bytes, and not as kilobytes, to avoid a situation like the above. -- Anand

[Dovecot] Password mismatch - SHA1 authentication problem.
by guard 09 Oct '06

09 Oct '06

Hello, I have problem with authentication. I'm using SHA1 passwords stored in MySQL. >From debug: Info: auth-worker(default): sql(test@mail, IP): query: SELECT password FROM vmail WHERE mail = 'test@mail' Info: auth-worker(default): sql(test@mail ,IP): Password mismatch Info: auth-worker(default): sql(test@mail ,IP): SHA1(dupadupa) != '2bca9dbe8a14811c687bb8c51c0e1cd14db8a018' I tried convert password to upper case, but it didn't help. Then I tried authentication in plain text and everything works fine... So, does dovecot crypt SHA1 using other method? I also use same SHA1 passwords to authenticate users in exim and it doesn't have any problem with that. I'm using mysql 5.0.24 and dovecot 1.0 rc7. Best regards, Tomasz Krynicki

[Dovecot] Dovecot behaviour when the server's file system fails (possible feature request)
by Timo Neuvonen 09 Oct '06

09 Oct '06

I've met a couple of times a situation, that there is something wrong with the mail server's operating system / file system, but Dovecot is still working, although it cannot any more access the mailbox files. The result is, that the imap mail client in the workstation automatically synchronises with the improperly empty-looking mailbox, effectively deleting everything previously loaded into the workstation's mail client (eg. Outlook Express) when using imap protocol. This is very annoying, especially when the workstation isn't connected with a high-speed-enough connection, since after the server is properly brought up again, reloading all the contents of the improperly emptied mail client may take considerable amount of time. This is especially the case, if the workstation has kind of mobile connection (eg. gprs) with very limited bandwith -in that case the sychronizing of eg. 20MB account may take at least from half an hour to more than one hour, and in some cases (eg. gprs roaming) also cost considerable amount of money (gprs data transfer may cost from eg. 5 to over 10 euros or dollars per megabyte, when roaming outside the phone operator's own network). So, is there currently a way to configure Dovecot in a way it would recognize that the mailbox actually is not accessible, and in that case it would return an error message to the mail client instead of returning "empty mailbox"? Of course, a smart enough mail client might also ask something from the user, but that seems not be the case either... If this behavious cannot be changed with the current configuration options, then a kind feature request to the developer: Would it be possible to change the behaviour of Dovecot when it actually can not access the mailbox files? Although the actual problem in this case is outside Dovecot, this kind of improvement would greatly improve the error tolerance of the whole system. -- TiN

[Dovecot] fd leak in 1.0rc7?
by Quentin Garnier 09 Oct '06

09 Oct '06

Hi, I just upgraded a 0.99 installation to 1.0rc7 (going from mbox to maildir along the way, but that's another story), and I'm seeing a rather fast fd quick; I already had to restart dovecot once, after a few hours. What is leaked are pipes, left open on the master dovecot process while the other end is long gone. I can't tell right now if it happens for every single login process spawned (either pop3 or imap), but at least a lot of them. FWIW, I'm running dovecot 1.0rc7 on NetBSD 2.0.3_STABLE. I'll try debugging tomorrow, but if anyone has an idea what happens in the meantime, I'm all hears. -- Quentin Garnier - cube(a)cubidou.net - cube(a)NetBSD.org "When I find the controls, I'll go where I like, I'll know where I want to be, but maybe for now I'll stay right here on a silent sea."

[Dovecot] Pop3s duplicates
by Mark Adams 09 Oct '06

09 Oct '06

Hi, dovecot 1.0 rc6 Can someone please advise on my interpretation of the following logs, Users are reporting duplicate email coming through to their inbox. (user@domain replaced actual username and domain) There are also reports of the connection seemingly freezing whilst the emails are being downloaded (pausing at a certain amount of kB then continuing after a minute or 2). info: pop3-login: Login: user=<user@domain>, method=PLAIN, rip=89.192.*.**, lip=172.16.22.10, TLS info: POP3(user@domain): Disconnected top=0/0, retr=4/183443, del=0/313, size=83779942 info: pop3-login: Login: user=<user@domain>, method=PLAIN, rip=89.192.*.**, lip=172.16.22.10, TLS info: POP3(user@domain): Disconnected top=0/0, retr=3/183443, del=0/322, size=84201570 In the first instance the user downloaded 4 emails totalling 183443 bytes leaving 313 messages on the server. (outlook 2003 set to leave a copy of messages on the server) second instance user downloaded 3 emails, exactly the same amount of bytes and left 322 messages on the server. Does this mean the users connection was interrupted when downloading the original emails and they attempted to be sent again a second time? how could it be that there are 9 emails left on the server if only 3 extra were downloaded? Any help on this would be much appreciated. Thanks, Mark

[Dovecot] coding techniques
by David Lee 09 Oct '06

09 Oct '06

Whilst debugging a problem in dovecot LDA over the last few days, I came across two different issues in coding techniques. (Note: Please don't take this negatively; my intent is both positive and constructive!) The front page of the website www.dovecot.org says: "it uses several coding techniques to avoid most of the common pitfalls" So I hope it is OK to follow the spirit of that with some suggestions. The two issues I encountered both seem to be fairly easy holes to fall into, and yet equally easy to avoid in the first place by using established C practices. Firstly, many 'if' statements having a single statement (whether in then or else part) are currently written in a short-cut fashion: if (condition) statement 1; else statement 2; This, though technically legal, is potentially lethal when inserting (say) debugging statements. Without diligence it is all to easy to produce: if (condition) debug 1a; statement 1; debug 1b; else debug 2a; statement 2; debug 2b; A simple edit that looks, layout-wise, as if it would do the right thing (and do in Python!); but actually radically changes the execution flow. (This is left as an exercise to the reader... to demonstrate the point.) Could I suggest that the relevant brackets be always used as a matter of course? Something like: if (condition) { statement 1; } else { statement 2; } Then the insertion of debug statements doesn't inflict surprise. (No, I didn't fall into this hole. But it is a trap waiting to happen.) Secondly, code duplication. To give one example: 'get_var_expand_table()' appears in both 'deliver/deliver.c' and 'master/mail-process.c'. (There is also a similar looking function in 'auth/auth-request.c'.) Perhaps consideration should be given to merging such instances. For instance, my woes with "%i"-expansion being treated differently in mail-reading and mail-delivery would likely never have arisen if common code had been used. I hope that helps (constructively!).

[Dovecot] rc7 crashing under heavy load
by Jeff A. Earickson 09 Oct '06

09 Oct '06

Help! Our students are back and they are pounding my dovecot server to death (ie "Login process died too early - shutting down" or "too many open files" type crash). I've had my third crash today. My setup: Solaris 10, imap and imaps, 3K users coming in via horde webmail. My current connection settings are: login_max_processes_count = 2048 login_max_connections = 4096 Q: Does raising these limits actually make my problem worse or better? Are there any other variables that I should change to prevent the "too many open files"? Suggestions? Jeff Earickson Colby College

[Dovecot] sent message not always saved in imap sent folder
by Ian Mortimer 09 Oct '06

09 Oct '06

Users who have their sent folder on the imap server report that sometimes a sent message is saved locally instead of on the server. This is the error from evolution: Error while performing operation. Failed to append to whoever@imap.server:Sent: Server unexpectedly disconnected: Unknown error Appending to local `Sent' folder instead.. We're seeing this with more than one client: evolution (linux) and thunderbird (OS X). It only happens occasionally but often enough to be annoying. It could be because the user's Sent folders are in their home directories which are NFS mounted. Are there any dovecot settings which might help? Thanks -- Ian

[Dovecot] Lost email (inbox) TWICE
by Sezer Yalcin 09 Oct '06

09 Oct '06

I have been losing my inbox. It happened twice. (2 days ago and just half an hour ago) I am using RHEL 4.0 with dovecot-0.99.11-4.EL4 System uses sendmail + procmail, dovecot is up and running. Here is how it happened: I was using Mozilla Firefox with IMAP. At the same time, I logged in from Squirrel Webmail in IMAP to the same account. Squirrel mail did not show my inbox contents. And I turned back to Thunderbird and it said, ' an error has occurred and logged to system log' and INBOX WAS LOST! squirrelmail 1.4.6 and mozilla thunderbird version 1.5.0.7 I checked server log, I see I log in but there are no further logs. This happened 2 days ago, I was wondering what the hell happened. I did not have any issues before. However recently we had a hard drive crash and all home folders are restored from backups. I assume it can be related to this. My inbox and imap folders are all in mbox format. I believe dovecot could not write to log or had something unexpected which lead to loss of inbox. There were no configuration issues and all mail system including dovecot were working fine. Now it works fine as well, but I believe it will lose inbox folder again. Has anybody experienced this? Any suggestions to recover inbox? File was reset to 0 bytes (could be deleted as well), when i did 'stat' on file, there was a file with 1 new message, all were lost. Thank you. Sezer

[Dovecot] Using NFS - which OS would you chose
by Jonathan 09 Oct '06

09 Oct '06

Hi, I'm still looking at a large (under 100,000) user deployment of Dovecot, with a NetApp NFS server as the back-end storage. I've read a few remarks about needing the latest NFS patches from Trond Myklebust to prevent lock-ups. My management would be happiest with a vendor-supported distribution (and especially Suse Linux Enterprise Server 9 or 10). We will be running on an x86 platform. Under these circumstances, which operating system/distribution would you choose? And why?

[Dovecot] Cache fields
by Tony Kay 09 Oct '06

09 Oct '06

Hi, We are using Dovecot with maildir, and the mail client requests flags, internaldate, and uid for all messages on folder open, which on average takes 3 seconds, but for large folders is much longer. It seems like I want mail_cache_fields to include "flags", but which date corresponds to internaldate? date.received? Is UID always cached for messages, or does it have to read through the directory to get them? Are there other optimizations I can do that will improve the speed of folder opens? -- Anthony Kay University Computing Center (541) 346-1719 GPG Fingerprint: B0DB D46A 60AF FAE7 A94A 5075 0CB4 4D88 9F4F 7F09 This isn't right.

[Dovecot] Date Received question

I migrated from Courier to Dovecot, and today I notice that all my "date received" fields in my client (apple mail) show as the approx date/time of the migration rather than when the emails were received from the smtp server. Is this expected behavior? I normally sort by received date rather than sent -- since I don't care when someone sends something as much as when i get it. But those fields are totally bogus now. .tim

In just two hours though the imap-login process is up to 33 MB, and continuing to grow. Is that normal? This particular server handles 1200 IMAP connections and 800 IMAPS connections concurrently on average. Bill

[Dovecot] Outlook "IMAP server closed connection"
by Mark Adams 08 Oct '06

08 Oct '06

Hi All, Dovecot 1.0rc2. Currently having a problem with Outlook clients popping up with the error; "Your IMAP server has closed the connection. This may occur if you have left the connection idle for to long" I initially though this would be the imap_client_workarounds = outlook-idle option, but this is currently set and always has been. I dont think this is a known issue that has been fixed with newer releases, as we have rc2 on another server that does not have this problem. Any help thankfully recieved. Regards, Mark

I'd ask from Postfix list.

[Dovecot] Add virtual users to the Dovecot configuration
by Jens E. Madsen Jr. 08 Oct '06

08 Oct '06

Dear Dovecot Mail List, I have used Dovecot for quite a while to service remote users on my SOHO network. A local not-for-profit asked about getting their own dedicated domain name for mail. I followed: http://www.howtoforge.com/linux_postfix_virtual_hosting to set up a virtual, but the article leaves out system accounts and I have not been able to access both system and virtual users at the same time. I have the following lines: default_mail_env = maildir:/var/spool/vmail/%d/%n/ which, when commented out, works for system users default_mail_env = mbox:~/mail/:INBOX=/var/spool/mail/%u which, when commented out, which works for virtual users If both are uncommented, only system users work. Wiki-ing and Googling, I learned that namespace could be applied to the problem. Here is the namespace from the configuration file. #namespace private { # Hierarchy separator to use. You should use the same separator for all # namespaces or some clients get confused. '/' is usually a good one. # The default however depends on the underlying mail storage format. #separator = # Prefix required to access this namespace. This needs to be different for # all namespaces. For example "Public/". #prefix = # Physical location of the mailbox. This is in same format as # default_mail_env, which is also the default for it. #location = # There can be only one INBOX, and this setting defines which namespace # has it. #inbox = yes # If namespace is hidden, it's not advertised to clients via NAMESPACE # extension or shown in LIST replies. This is mostly useful when converting # from another server with different namespaces which you want to deprecate # but still keep working. For example you can create hidden namespaces with # prefixes "~/mail/", "~%u/mail/" and "mail/". #hidden = yes #} How do I specify which users use which namespace. Is there a good description of namespaces and how to use them? Thanks Jens
