[Dovecot] Problems with Upgrade from Courier
by Aaron Pettitt 20 Jan '11

20 Jan '11

I inherited a server from a previous employee. The server crashed so it was time to move everything over to another server. We have a web mail site and I installed everything running dovecot, postfix and roundcube. After I installed it, everything worked great when I created a new user. The new user could send and receive emails with no issues. I then copied the home directory over from the other server and ran the courier-dovecot migration script. It created the subscription files and the dovecot-uidlist files in each user (about 1000 total users). When I login as one of the existing users, it says that there is no mail in the mailbox. However, if I look at the user's cur and new folders, there is mail in those folders. If I send a new mail to the user, it does not show up in their inbox. If I look in their new folder, the new mail that I sent was delivered to that folder but it does not show up in their inbox. I've tried going to dovecot directly through telnet with the same results. I've been stuck for 2 days now so any help is greatly appreciated. Below is my dovecot.conf with all the comments removed. Thanks all! protocols = imap imaps disable_plaintext_auth = no log_path = '/var/log/dovecot/error.log' info_log_path = '/var/log/dovecot/info.log' log_timestamp = "%m/%d/%Y %H:%M:%S " #mail_location = maildir:~/ mail_location = maildir:/home/vmail/%d/%n/ mail_privileged_group = mail mail_debug = yes protocol imap { } protocol pop3 { } protocol managesieve { sieve_storage=~/sieve } protocol lda { log_path = /home/vmail/dovecot-deliver.log auth_socket_path = /var/run/dovecot/auth-master postmaster_address = postmaster(a)mybridemal.com mail_plugins = cmusieve global_script_path = /home/vmail/globalsieverc } auth_verbose = yes auth_debug = no auth_debug_passwords = no auth default { passdb sql { args = /etc/dovecot/dovecot-sql.conf } args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes } user = root path = /var/run/dovecot/auth-master mode = 0600 user = vmail #group = } client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } }

[Dovecot] Bug found, assertion failed
by Tobias Daucher 20 Jan '11

20 Jan '11

Hi there, We're running dovecot 2.06, with mdbox. Following message was in our syslog: Jan 20 09:26:48 servername dovecot: [ID 583609 mail.crit] imap(user): Panic: file istream-limit.c: line 79: assertion failed: (v_offset <= lstream->v_size) The problem could be solved on client side, by just deleting the ImapMail-Folder in Thunderbird. Why? Thunderbird tried to move a message, that obviously wasn't there. Dovecot got killed and the message above was in the syslog. Connection was closed and Thunderbird told me the server is dead. Thunderbird tried this every few seconds, and there was no way to say thunderbird "stop try moving". So the only way was to delete thunderbirds mail cache. I think it would be very nice, if dovecot doesn't die, just because the client tries to move a message, which isn't there.

Go with a cluster filesystem such as OCFS or GFS2 and an inexpensive SAN > storage unit that supports mixed SSD and spinning storage such as the Nexsan > SATABoy with 2GB cache: http://www.nexsan.com/sataboy.php I can't speak for OCFS2, but after several years' experience with the filesystem I strongly recommend NOT using GFS/GFS2. Its locking model is incredibly slow (500 locks/second on a filesystem mounted with quotas enabled and noatime) and results in dire performance - plus there's a known crash vulnerability if files are repeatedly renamed in large directories (this bites us regularly...) GFS2 isn't an "enterprise" filesystem by any stretch of the imagination, despite what a number of enthusiastic salespeople might try to convince you of. We're lucky to keep the GFS servers up for more than a week at a time.

[Dovecot] Upgrading from 1.2 to 2.0
by list＠airstreamcomm.net 20 Jan '11

20 Jan '11

Greetings Dovecot mailing list! We are an ISP that recently migrated from Courier to Dovecot, and are looking at the next round of upgrades. Hoping that we could get pointed to some documentation or get a general list of best practices for an upgrade from 1.2.13 to 2.0.9. Our current environment consists of four Dovecot machines that share an NFS backend hosting POP and IMAP. Our biggest question is whether we can support a rolling upgrade from 1.2.13 to 2.0.9, or if it would need to be an all for one cut. Thanks in advance.

Re: [Dovecot] Duplicate mail for forwards (dovecot+postfix+postfixadmin)

Cool, thank you Patrick! Must have missed that somehow. I put the setting in main.cf, "receive_override_options = no_address_mappings", right after 'content_filter' (running amavisd on a separate port) and it seems to have fixed the problem. -- Darek On Tue, Jan 18, 2011 at 7:05 PM, Patrick Westenberg <pw(a)wk-serv.de> wrote: > Darek M schrieb: > >> Anyone have an idea of what I should be looking at in a situation like >> this?

[Dovecot] Pigeonhole 2.2 build issue on arm
by Tom Talpey 19 Jan '11

19 Jan '11

When building Pigeonhole 2.2 for ARM, the following warnings are produced: uri-mailto.c: In function '_parse_hex_value': uri-mailto.c:139: warning: comparison is always false due to limited range of data type uri-mailto.c:145: warning: comparison is always false due to limited range of data type The problem is a test assuming that char is a signed type : static inline int _decode_hex_digit(char digit) { ... static bool _parse_hex_value(const char **in, char *out) { char value; // <<--- change to "int". if ( **in == '\0' || (value=_decode_hex_digit(**in)) < 0 ) return FALSE; *out = value << 4; (*in)++; if ( **in == '\0' || (value=_decode_hex_digit(**in)) < 0 ) return FALSE; This is untested, but I changed the "char value" to "int value" to correct the signed comparisons. There are no warnings when building for x86 in either case, btw. Also, the two tests for "**in == '\0'" seem to be unnecessary?

[Dovecot] Problem with seeing mail after Upgrade from Courier
by apettitt 19 Jan '11

19 Jan '11

I created a new server for a webmail system because the old server crashed. When I created the server, I installed Dovecot and the old server had Courier. On the new server, I'm doing virtual users where the old one created system users. I moved all the folders over for all the users on to the new server and ran the Courier-Dovecot migration script. The files were created successfully with no issues. The issue I'm having now is that Dovecot is not seeing any mail in the user's directory. If I create a new user, it can send and receive mail with no problems. If I send an email to an existing user, it gets delivered to the new folder but dovecot does not see anything in the new folder. There is also mail in the curr folder that dovecot does not see. I'm using Roundcube as a webmail client but I've also tried using Telnet with the same results. Any ideas? -- View this message in context: http://old.nabble.com/Problem-with-seeing-mail-after-Upgrade-from-Courier-t… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Duplicate mail for forwards (dovecot+postfix+postfixadmin)
by Darek M 19 Jan '11

19 Jan '11

Dovecot 1.2.11, using postfixAdmin 2.3 to manage, basically using the postfixadmin schema and sql queries during install. - If I set a forward for an account to go to a remote email address, no dupes. - If I set a forward for an account to go to an email address on the same system, I get a dupe in the inbox of the second address. So if account1(a)domain.com has account2(a)domain.com as a forward, account2@ receives two copies of the same message, completely identical, same message IDs, same md5 sum. If I add account3@ into the mix, account3@ will also receive two copies of each message. I will also get a duplicate if I forward mail to account(a)anotherdomain.com, where anotherdomain.com is also hosted on the same system. account1(a)domain.com receives one copy. Here is the Dovecot log: Jan 18 17:24:40 deliver(account2(a)domain.com): Info: msgid=<4D361323.3040000(a)srvr.net>: saved mail to INBOX Jan 18 17:24:40 deliver(account1(a)domain.com): Info: msgid=<4D361323.3040000(a)srvr.net>: saved mail to INBOX Jan 18 17:24:40 deliver(account2(a)domain.com): Info: msgid=<4D361323.3040000(a)srvr.net>: saved mail to INBOX Postfix logs only show one delivery for each message, and since the headers aren't changed at all, I think the lda is at fault here.

[Dovecot] Dovecor 1.2 : Command output: Fatal: Unknown argument: flags=DRhu Usage: deliver [-c <config file>] [-a <address>] [-d <username>] [-p <path>] [-f <envelope sender>] [-m <mailbox>] [-n] [-s] [-e] [-k] )

Hi there, I changed postfix to pass email to spamassassin, and then deliver to dovecot LDA. It fails to deliver. The current entry in master.cf now reads: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -d ${recipient} smtp inet n - - - - smtpd -o content_filter=spamassassin spamassassin unix - n n - - pipe user=nobody argv=/usr/bin/spamc -f -e /usr/sbin/sendmail -oi -f ${sender} ${recipient} This is the same as I had to afore I factored in spamassassin. The error message is this:- Jan 18 16:30:44 logout postfix/pipe[28952]: 56AE58230A: to=<test(a)test.info>, relay=dovecot, delay=0.01, delays=0/0/0/0.01, dsn=5.3.0, status=bounced (command line usage error. Command output: Fatal: Unknown argument: flags=DRhu Usage: deliver [-c <config file>] [-a <address>] [-d <username>] [-p <path>] [-f <envelope sender>] [-m <mailbox>] [-n] [-s] [-e] [-k] ) Does anyone know which options I should have added to dovecot deliver?

[Dovecot] v2.0.9 released
by Timo Sirainen 18 Jan '11

18 Jan '11

http://dovecot.org/releases/2.0/dovecot-2.0.9.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.9.tar.gz.sig I'm still lagging behind in my email, but I guess it's time to release v2.0.9 anyway. - Linux: Fixed a high system CPU usage / high context switch count performance problem - Maildir: Avoid unnecessarily reading dovecot-uidlist while opening mailbox. - Maildir: Fixed renaming child mailboxes when namespace had a prefix. - mdbox: Don't leave partially written messages to mdbox files when aborting saving. - Fixed master user logins when using userdb prefetch - lda: Fixed a crash when trying to send "out of quota" reply - lmtp: If delivering duplicate messages to same user's INBOX, create different GUIDs for them. This helps to avoid duplicate POP3 UIDLs when pop3_uidl_format=%g. - virtual storage: Fixed saving multiple mails in a transaction (e.g. copy multiple messages). - dsync: Saved messages' save-date was set to 1970-01-01.

[Dovecot] Question about indexes and maildir/sdbox/mdbox
by Javier de Miguel Rodríguez 18 Jan '11

18 Jan '11

Hello We are now running dovecot 2.0.9 with indexes in a ram disk and maildir storage in a test system. We have the following questions: - If there is a power outage / kernel crash, we will lose the content of ramdisk. We have tested that indexes are regenerated when a user logs in via imap, so e-mail access will be "slower" after a power outage / kernel crash, but everything should work as expected (TM). Are we missing something? - We are evaluating migrating from maildir to dbox. There are two alternatives: sdbox and mdbox. Reading about dbox in the wiki (http://wiki2.dovecot.org/MailboxFormat/dbox) we see that using a ram disk for indexes for mdbox is a really bad idea: /"Note that with dbox the Index files actually contain significant data which is held nowhere else. Index files for both *single-dbox* and *multi-dbox* contain message flags and keywords. For *multi-dbox*, the index file also contains the map_uids which link (via the "map index") to the actual message data. This data cannot be automatically recreated, so it is important that Index files are treated with the same care as message data files."/ So in mdbox we should not use a ramdisk for indexes. But what about sdbox? sdbox indexes work as maildir indexes? Are sdbox indexes bigger than maildir indexes? Thank you very much for your support Regards Javier

[Dovecot] Running two different versions of Dovecot (was: making folders unmovable)
by Dave 17 Jan '11

17 Jan '11

OK, so I decided to go ahead and just upgrade to the latest 1 series Dovecot and see if that solves my ACL/config issues I've been having. (I tried compiling 2.0.9, but it errored out and I assume that's because it's a pretty old machine/compiler.) Anyway, 1.2.16 compiled fine, and I installed it in another location from the currently running 1.1 series install. I have this new install running (IMAP) on a non-standard port while I test it out, and it starts fine and all seems well. However, I'm wondering, is it OK to run it and have it look at the same Maildir mailboxes as the currently running 1.1 series install? Does that have the potential to mess with indexes or change anything in a bad way? (FWIW, I tried it briefly, and after changing the port number in and restarting my mail client [Thunderbird], it had trouble pulling up the mailbox I was trying to access.) David

This is pretty much what I do with the mail domain I administer. I've set the INBOX with a modest quota, and a personal mail folder with a generous quota. I encourage users to keep their INBOX as a "working set", and archive the rest using any method they prefer. It forces users to process their Email (or at least their INBOX). and keeps packratting in check. Super-big INBOX quotas seem to encourage wasteful habits. I've helped some users clean out their mailboxes and was surpised at the amount of junk being kept for years and years. Apart from a few users moaning about their meager INBOX, this policy works out fairly well. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Virtual mailboxes do not look into subfolders

Hi all, I have virtual mailboxes set up as "Smart Folders" to show me messages tagged with certain keywords. For example: # ~/Maildir-virtual/fwp/dovecot-virtual File MailingLists/* KEYWORD @fwp Messages get picked up from the File mailbox, but not for the sub-mailboxes inside the MailingLists mailbox. What am I doing wrong? Wrong separator? And how can I debug this? Everything else is working fine. Thanks a lot! Paul
