Hi Timo... It's happens some strange issue with my maildir using NFS. If i use a Local Hard disk, i don't get any of this messages about memory error. Jan 12 10:57:50 brc dovecot: imap(alex(a)exemplo.com.br): Error: opendir(/storage/nfs/3/emexis/messages/ exemplo.com.br/alex/Maildir/.Drafts/new) failed: Cannot allocate memory Jan 12 10:57:51 brc last message repeated 4 times Jan 12 10:57:59 brc dovecot: imap(alex(a)exemplo.com.br): Fatal: block_alloc(262144): Out of memory Jan 12 10:57:59 brc dovecot: imap(alex(a)exemplo.com.br): Error: Raw backtrace: /opt/addons/lib/dovecot/libdovecot.so.0 [0xb768fcbe] -> /opt/addons/lib/dovecot/libdovecot.so.0 [0xb768fd1d] -> /opt/addons/lib/dovecot/libdovecot.so.0 [0xb768f273] -> /opt/addons/lib/dovecot/libdovecot.so.0 [0xb76a0183] -> /opt/addons/lib/dovecot/libdovecot.so.0 [0xb76a01cc] -> /opt/addons/lib/dovecot/libdovecot.so.0(p_strdup+0x40) [0xb76ad980] -> /opt/addons/lib/dovecot/libdovecot-storage.so.0(maildir_save_add+0x7c) [0xb7717f0c] -> /opt/addons/lib/dovecot/libdovecot-storage.so.0(maildir_copy+0x18d) [0xb7719bbd] -> /opt/addons/lib/dovecot/lib20_emexis_uis_plugin.so [0xb74fda6a] -> /opt/addons/lib/dovecot/libdovecot-storage.so.0(mailbox_copy+0x58) [0xb76ea258] -> dovecot/imap(cmd_copy+0x1cf) [0x804f87f] -> dovecot/imap(cmd_uid+0x7f) [0x80551bf] -> dovecot/imap [0x8055f0c] -> dovecot/imap [0x8055fbb] -> dovecot/imap(client_handle_input+0x3f) [0x805610f] -> dovecot/imap(client_input+0x5f) [0x8056acf] -> /opt/addons/lib/dovecot/libdo Jan 12 10:57:59 brc dovecot: master: Error: service(imap): child 28315 returned error 83 (Out of memory (vsz_limit=256 MB, you may need to increase it)) I Try to increase the vsz_limit in imap to 2048 MB, and i try too , put 0 MB (like no limit) and i still get this same error (only change the vsz_limit to my write limit). What is most used "Shared Disk" in Dovecot ? Tks Timo !!

[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. This is the entry for the account in the 'alias' table ======================== mysql> select * from alias where address='account1(a)domain.com'; +-----------------------+----------------------------------------+------------+---------------------+---------------------+--------+ | address | goto | domain | created | modified | active | +-----------------------+----------------------------------------+------------+---------------------+---------------------+--------+ | account1(a)domain.com | account1@domain.com,account2@domain.com | nyinet.com | 2010-11-28 18:07:40 | 2011-01-18 17:04:03 | 1 | Anyone have an idea of what I should be looking at in a situation like this? Does the 'goto' field look fine? -- Darek

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
