[Dovecot] maildir and end-of-line encoding
by Christoph Anton Mitterer 23 Nov '12

23 Nov '12

Hi. I just wondered, the following: My MDA may get mails that use LF or CR/LF end of line encodings and deliver them into maildirs. I couldn't find any information about, whether one should or must convert all into one format, cause AFAIK at least on the IMAP side, CR/LF is always used? How does this work on the maildir/backend side of dovcot? Can it work with both and simply automatically convert LF into CR/LF? Thanks, Chris.

Thank you. One thing that still doesn't work is subscribing to all mailboxes via "*", I guess because the folder names start with "." but dovecot mailbbox subscribe wants it without a starting "."

[Dovecot] XMLRPC anyone?

Hi, Is there any code around that lets Dovecot (2.x) aauthenticate via a XMLRPC server (which connects to a LDAP server) instead of going directly to a LDAP server? It could give much more flexibility. TIA Egbert Jan, NL

[Dovecot] v2.1 memory usage
by Timo Sirainen 21 Nov '12

21 Nov '12

v2.1's imap/pop3 processes are linked with OpenSSL by default, because of imapc/pop3c storages. I wonder if you notice any actual (system-global) memory usage reduction when compiling without those and you have thousands of imap processes? ./configure --with-storages=mdbox sdbox maildir mbox cydir I guess I could try it myself also but maybe someone else wanting to reduce memory usage is quicker? :) Related to that, you can look at where imap processes' memory goes with: http://dovecot.org/tools/linux-maps-parse-imap.pl I don't know how much memory those (writable!) file-backed memory areas actually use per-process. Maybe nothing, maybe something..

[Dovecot] users mail folders have to be subscribed
by Andre Bischof 20 Nov '12

20 Nov '12

Hi, I did a migration from cyrus 2.2 to dovecot (fresh installation, details below) via cyrus2dovecot from FU Berlin. That worked, but I first was missing mails in subfolders ander Inbox. No I detected that they are in the users Maildir in folders in his directory. They are listed when using telnet: * LIST (\HasChildren) "." "INBOX.ebay" * LIST (\HasNoChildren) "." "INBOX.ebay.xj" But they are not shown in thunderbird, I have to subscribe to them one by one. I probably did something wrong and maybe messed up with namespace and seperator settings - it would be great if one could lead me out of that. The wiki was a great help installing and configuring everything, but now I'm stuck. I use dovecot 2.1.7 under Ubuntu 12.10: # dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.5.0-18-generic x86_64 Ubuntu 12.10 auth_verbose = yes mail_debug = yes mail_location = maildir:~/Maildir managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation s ubaddress comparator-i;ascii-numeric relational regex imap4flags copy include variab les body enotify environment mailbox date ihave namespace inbox { inbox = yes list = yes location = prefix = separator = . type = private } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = postmaster@localhost protocols = imap pop3 sieve service auth { unix_listener /var/spool/postfix/private/dovecot-auth { group = postfix mode = 0660 user = postfix } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_cipher_list = ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { imap_client_workarounds = delay-newmail mail_max_userip_connections = 10 } protocol pop3 { mail_max_userip_connections = 10 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_cipher_list = ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { imap_client_workarounds = delay-newmail mail_max_userip_connections = 10 } protocol pop3 { mail_max_userip_connections = 10 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { deliver_log_format = msgid=%m: %$ mail_plugins = sieve sieve postmaster_address = postmaster quota_full_tempfail = yes rejection_reason = Your message to <%t> was automatically rejected:%n%r } Any help is greatly appreciated!

[Dovecot] upgrade 1.0.15 -> 2.1.7: MBOX index compatibility and performance
by Benoit Branciard 19 Nov '12

19 Nov '12

Hi, we just upgraded our mailserver from Dovecot 1.0.15 to Dovecot 2.1.7. We use MBOX format (due to legacy compatibility), system users, PAM+GSSAPI auth, filesystem quotas, and indexes located on a separate filesystem: mail_location = mbox:~/mail:INBOX=~/mail/INBOX:INDEX=/var/cache/dovecot/indexes/%16Hu/%u The 2.1.7 configuration files have been rewritten based on default templates instead of converting it from 1.0.15. The server has ~8000 mailboxes and about ~2000 simultaneous IMAP/POP active connexions. The problem is: - indexes seem to be rebuilt: first IMAP/POP connexion for each user thows lots of error messages in the log, and the global index size decreases. Example error log: Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Cached message size larger than expected (27884 > 27855) Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Corrupted index cache file /var/cache/dovecot/indexes/4/myuser/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 4414 Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Cached message size larger than expected (27884 > 27855) Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Corrupted index cache file /var/cache/dovecot/indexes/4/myuser/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 4414 Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Cached message size larger than expected (27884 > 27855) Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Corrupted index cache file /var/cache/dovecot/indexes/4/myuser/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 4414 Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Cached message size larger than expected (27884 > 27855) Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Corrupted index cache file /var/cache/dovecot/indexes/4/myuser/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 4414 Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: copy: i_stream_read() failed: Input/output error Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Cached message size larger than expected (27884 > 27855) Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Corrupted index cache file /var/cache/dovecot/indexes/4/myuser/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 4414 - load average is extremely high (more than 10x the usual one), resulting from an significant increase of disk I/O, and for now (4h after the "monday rush") this doesn't seem to decrease.

[Dovecot] advices for a new installation
by Surviet Amine 18 Nov '12

18 Nov '12

hello everyone, first of all, please forgive my bad english skill, I live in France. On our "old" Dovecot 1.x architecture, we have NFS shares between the front servers (MTA, IMAP...) and mail storage server. I've read some wiki2 pages that present the new director and imap proxy. But I'm still don't see things clearly, so I post here to have your advices to set-up a new mail architecture. The hardware we have : - 24x hard drives in a SAS bay - this bay is directly attached via SAS to a server that I'll call : mail storage server - 2 others servers run ProxMox Virtual Environment The PVE will help us to get many virtual servers : - MX : "mail in" servers - IMAP/POP : our hosted clients services These clients may come from webmail (RoundCube) and others clients (Outlook, Thunderbird, mobile clients...) - RoundCube webmail - MySQL server (hosts in databases accounts and settings for Postfix, Dovecot and RoundCube) - maybe antivirus and antispam servers I've read several threads about NFS and IMAP issues. So I decided to not keeping it. In this scenario, I've tried for the mail receiving part : - front-end (postfix lmtp-client) to mail storage server (lmtp server) that seems to runs fine, now i'll must try to add antispam and antivirus scans Now, for the IMAP part, could you, please tell me, if it is better to : - have several IMAP frontend servers that proxy to the mail storage server or - still keeps NFS between the mail storage server and the frontends Dovecot ? On our Dovecot 1.x webmail use imapproxy. I've read that others proxies exist. We have used for a limited time Perdition. What is the differences between imapproxy, Perdition, nginx imap proxy and Dovecot proxy ? Thanks for sharing your experience of "large mail service" that are solid enought to be scaled.

[Dovecot] Different Mechanism for POP3
by Tim Smith 18 Nov '12

18 Nov '12

Just wondered if there was a way of making the PLAIN an authentication method for POP3S transactions only without making this an option for IMAP? I am attempting to connect to a POP3S server through the GMail interface available through "Accounts and Import". The issue is that there does not seem to be an option to specify the type of mechanism within their interface so I think I have to offer PLAIN along with SSL. Has anyone else had any experience of using the GMail import settings? -- Tim Smith Tel: 01423 564 078 Mob: 07984 398 299 Email: info(a)titan21.co.uk Web: www.titan21.co.uk

[Dovecot] couple questions about dovecot
by Raan Young 18 Nov '12

18 Nov '12

I am attempting to migrate an ancient IMAP server to Dovecot 2.0.9 running on CentOS 6.3, while trying to minimize the impact on users. Most are using Outlook. I have everything working, but have run into a couple of problems, neither horrible, but both weird. It started when I noticed Outlook shows the .subscriptions file in the folder listing. I figured out a way to prevent that (see below), but then decided to attempt the same tactic to move the .imap index structure out of the folder tree and ran into an interesting side-effect. The .subscriptions issue would seem to be a bug, since the documentation I found implies Dovecot should be hiding it from list requests - as it does for the .imap index structure. I made a workaround by using the below mail_location setting. This puts the .subscriptions file above the imap folder structure and hence outside the list scope. mail_location = mbox:~/imap:INBOX=~/mbox:CONTROL=~:INDEX=~/.imap You'll note I have also moved the .imap index. This works, but the full path to the index files has extra layers of .imap. For example, if a folder tree of imap/A/B/C/D exists, where D is the actual mbox format message file, then the index files are stored in .imap/A/B/C/.imap/D. Don't know if this is a bug or I'm misunderstanding something. Can you provide any insight or better solutions for either issue? Some clients are also using iPhones and/or roundcubemail for web access. Those do not have the .subscriptions issue. Raan

The directories change their content not for weeks. It is a test environment. but in one of the folders are more than 13000 mails (the Faxbox). Currently 3 of 13 folders are affected. I thought that it may be due to the size, but it is not the largest folders. For normal mail boxes I have not observed this effect. a3 EXAMINE Public.faxe * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS ()] Read-only mailbox. * 0 EXISTS * 0 RECENT * OK [UIDVALIDITY 1349419566] UIDs valid * OK [UIDNEXT 141737] Predicted next UID * OK [HIGHESTMODSEQ 5] Highest Delete indexes.... /var/mail/indexes/........../public# rm -r .faxe/ a3 EXAMINE Public.faxe * OK [CLOSED] Previous mailbox closed. * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS ()] Read-only mailbox. * 13778 EXISTS * 0 RECENT * OK [UIDVALIDITY 1349419566] UIDs valid * OK [UIDNEXT 141737] Predicted next UID * OK [NOMODSEQ] No permanent modsequences i would like to show you log files but i didn't see any error message.

[Dovecot] multiple users to same e-mail account with ldap authentication
by Marco Gatti 14 Nov '12

14 Nov '12

Hi, I was looking for a particular case of dovecot configuration I cannot find anywhere. Is there a way dovecot can authenticate via ldap different windows 2008 AD users that have access to the same e-mail account (like user authorization in ms exchange)? For example I want to extend AD schema to let users have 10 email accounts (with multiple domain support). If they are private accounts I think there is no problem at all. But if I want two or more users to access the same mail account what happens? Can I do it with dovecot? Or should I create AD groups and add members to that, to let user access the same mail account? Cheers -- Marco

Re: [Dovecot] IPhone wont delete IMAP messages from dovecot mailbox
by tibby＠tibby.hu 14 Nov '12

14 Nov '12

Hello! I've got dovecot running with postfix. Have virtual users under vmail folder. When I connect with outlook, I can read, delete messages. When I sign on with webmail, also can delete messages, Mutt is working as well on the mail server, can delete messages. Once the message is deleted it moves to the trash. Works as it supposed to. But on Iphone, when I add a mail user, got the mailbox synced with IMAP I can see the INBOX, but when I delete a message, get this error: "Unable to Move Message The message could not be moved to the mailbox Trash." http://www.netchimp.co.uk/webdesign/wp-content/uploads/2011/12/iphone_unabl… What causing this problem? Please Help.

[Dovecot] Dovecot 2.1.10
by Ralf Zimmermann 14 Nov '12

14 Nov '12

Hi all, I've a problem with dovecot-2.1.10. At time we use dovecot-1.2 without zlib. We setup a new server with dovecot 2.1.10. After syncing the emails everything looks fine. But if we use zlib plugin all new emails have no content. There are a lot of "Error: Maildir filename has wrong S value" log entrys. So we have compiled dovecot-2.0.18 and we use exactly the same configuration. Everything works. What can be our problem with version 2.1.10? Greets Ralf

[Dovecot] dovecot lost mail! Cause?
by Lukas Haase 14 Nov '12

14 Nov '12

Hi, After using dovecot for several years now, today happend something which makes me really feel unconfortable: An email received was just not delivered properly, or, is lost! The mail (from an external server) was sent to two local mailboxes, user1 and user2. user1 received the message but for user2, it *magically* disappeared. MTA is exim4 which definitely processed the messages and handed over to dovecot deliver: 2012-11-12 07:28:21 1TXnVG-00053I-GD SA: [...] id=8644593.887351352701 685934.JavaMail 2012-11-12 07:28:21 1TXnVG-00053I-GD => user1 <user1(a)example.com> R=dovecot T=dovecot_pipe 2012-11-12 07:28:21 1TXnVG-00053I-GD => user2 <user2(a)example.com> R=dovecot T=dovecot_pipe 2012-11-12 07:28:21 1TXnVG-00053I-GD Completed Also, the log of dovecot tells that the mail should have been stored: Nov 12 07:28:21 mail dovecot: deliver(user1): sieve: msgid=<8644593.887351352701685934.JavaMail>: stored mail into mailbox 'INBOX' Nov 12 07:28:21 mail dovecot: deliver(user2): sieve: msgid=<8644593.887351352701685934.JavaMail.orbitz>: stored mail into mailbox 'INBOX' user1 received the mail but user2 not. Since user2 is myself, I *know* that I did not accidently delete any mail or something like that. It was just never received! Disk space is 3GB left, so enough. So I grepped the whole Maildir of user2 for the message ID. There is only one match in the dovecot.index.cache and within that, the most important data of the mail (Message ID, Date, Sender, Receiver, Subject) appears. But apart from that, not a single file! Is there hope to ever find out why what was going wrong here? It feels me veeeeeeeeery unconfortable because from now on I can never be sure any more that all my mails are really received :( :( However, as I said, my mail system processed maybe millions of messages the past 8 years. Although, I can not be sure if that was the case ... :( And help greatly appreciated! Luke PS: Dovecot version 1.2.15 (Debian 6.0.6) with Maildir backend on local harddrive. No NFS, nothing which can go wrong ... PPS: Original log files, just named replaced for privacy.
