[Dovecot] Zlib maildir reindex bug?
by Richard Platel 15 Jan '13

15 Jan '13

Hi Running dovecot 2.1.7 (from debian repo). We have some old compressed maildir messages with the wrong S= size in the filename (our fault). If I delete index files, log in to the mailbox and try to FETCH the bad message, dovecot complains about the incorrect message size, attempts to fix the filename and disconnects the client. However, it changes the filesize to the size of the message on disk, not the message's uncompressed size. For subsequent clients, the FETCH works, but dovecot logs an error (and maybe re-indexes the mailbox?) and the message UID changes.

Any other hints? If the UIDs are just headers, why don't you simply checksum without them: sed -e '/^Whatever-header:/d' < $file | md5sum grep -Ev '^Whatever-header:' < $file | md5sum Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] sieve reject to wrong address?
by Felix Rubio Dalmau 15 Jan '13

15 Jan '13

Hi all, I have succeed in setting up postfix (to send/receive emails), dovecot to access the folders via IMAP, all using TLS and sieve under dovecot to manage filters. I have also set up a sieve rule to reject those mails whose size exceeds 2 MB... and I'm really proud of everything, because it is my first time!! However, when rejecting the mail, instead of sending a mail saying "I'm sorry blah, blah, blah" to the originary sender, it is sent to the final recipient (that is, me). Do you know how to solve it? Is it a problem from sieve or dovecot? I think is some misconfiguration of my dovecot installation, because the sieve rule is: ################ if size :over 2M { reject text: Ho sento, no accepto cap correu de mes de 2MB de tamany. Sisplau, puja els fitxers mes grans a un servidor i envia'm un link. Gracies. I'm sorry, I do not accept mail over 2 MB in size. Please upload larger files to a server and send me a link. Thanks. . ; } ################ dovecot log looks like: Jan 14 17:34:16 server dovecot: lda(felix@server): sieve: msgid=<201301141734.16203.felix@server>: rejected message from <felix@server> (reject) Jan 14 17:34:16 server postfix/cleanup[2011]: 2B59CB59: message- id=<dovecot-1358181256-51155-0@server> Jan 14 17:34:16 server postfix/pipe[2012]: 311AF4E0: to=<felix@server>, relay=dovecot, delay=1, delays=0.81/0.02/0/0.19, dsn=2.0.0, status=sent (delivered via dovecot service) Thank you! -- Felix Rubio Dalmau

[Dovecot] deleting duplicate mail?

Hello, Due to a misstake I got many duplicate emails in my inbox folder. They are stored in maildir format, so my initial thought was do simply md5sum the mail files and remove the duplicates. This doesnt work because the mails has differinf uids. Any other hints? -- Joakim Verona

[Dovecot] Dovecot SASL Client support?
by Charles Marcus 14 Jan '13

14 Jan '13

Hi all, I seem to recall mention of SASL client support either being added, but can't remember for sure. The wiki says nothing about Client support (now, or in the future)... http://wiki2.dovecot.org/Sasl So - is there support for it now? If not, is it planned for anytime soon? Thanks, -- Best regards, Charles

[Dovecot] load sbub-mailbox
by mourik jan heupink 14 Jan '13

14 Jan '13

Hi, We're about to migrate to dovecot (2.1.7 on wheezy), and I have a question about mail migration. Our 'old' imap mailserver will remain available, and has the same usernames/passwords as our future dovecot mailserver. The question: Is there an easy way to make the old mailboxes available under a subfolder (for example 'oldmail') in the mailboxes on the new mailserver? A bit like mounting an old homedirectory under an 'oldfiles' directory on a new fileserver. This way our users could access/migrate whatever folders they choose themselves, and we would not have migrate all messages to dovecot using scripts like imapcopy, etc. Perhaps using the proxy functionality..? Hope I make myself clear...? Regards, Mourik Jan

[Dovecot] I can not receive any mail
by Felix Rubio Dalmau 14 Jan '13

14 Jan '13

Hi everybody I'm trying to set-up an IMAPS mail server using dovecot (version 2.1.7) with virtual email accounts for my family. I have already ran through the mysql phase of the virtual email configuration (and I'm quite confident it works well, because I can send mails from the server using postfix to gmail, e.g.). However, I am stucked configuring dovecot. I don't know why is it not running properly. The symptoms are: a) When I connect by using my mail client (kmail), I don't get any error. b) When I ask kmail to check what authentication services are supported by the server, I see that it is able to connect to te server by looking to the server log. c) However, Inbox folder does never show up :S d) When I send any mail from gmail to my server, It is always refused under the reason that there is not such user in the machine (I am sure it is), and nothing shows up in the server log. Here is my configuration, just in case somebody can give it a look to help me figure out what's going on :S Thank you very much in advance. # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.6.9-1 x86_64 Debian 6.0.6 ext4 auth_cache_size = 1 M auth_debug = yes auth_mechanisms = plain login auth_verbose = yes auth_worker_max_count = 2 base_dir = /var/run/dovecot/ listen = * log_timestamp = "%Y-%m-%d %H:%M:%S " login_greeting = Dovecot ready. mail_debug = yes mail_location = maildir:/home/vmail/%d/%n/Maildir mail_privileged_group = vmail namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = type = private } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = postmaster(a)mysite.org protocols = " imap" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service imap-login { inet_listener imaps { port = 993 ssl = yes } process_min_avail = 0 service_count = 1 } service imap { process_limit = 5 } ssl = required ssl_cert = </etc/postfix/ssl/cert.pem ssl_key = </etc/postfix/ssl/cert.key userdb { args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes driver = static } verbose_ssl = yes protocol lda { mail_plugins = sieve } -- Felix Rubio Dalmau

[Dovecot] E-mail not being processed into Dovecot folders
by stalker 14 Jan '13

I have a new CentOS 6 server running Dovecot 2.0.9 It has current patches from CentOS. Pasted below are the version and output from dovecot -n When I run mail -s "test" username test <ctrl-D> mail is written to /var/spool/mail/username and not to /home/username/Maildir/ The user's client software, Thunderbird, logs in but since mail is not written to Maildir it thinks there is nothing (see paste below from /var/log/maillog) How do I get sendmail or what ever MTA processes mail to write to Maildir rather than /var/spool/sendmail?

[Dovecot] Anyone using dovecot obox?
by list＠airstreamcomm.net 14 Jan '13

14 Jan '13

Just looking for some input from other users of the obox (object storage) backend from dovecot.fi. - What challenges/problem were you trying to overcome/solve by using obox? - What kind of architecture did you deploy using obox? (e.g. distributed object storage for performance, or distributed for availability, geographic distribution of email services, etc.) - What complexities, single points of failure, documentation omissions can you highlight having deployed the obox storage architecture? - Did the obox backend support your email services as well as you expected or more? - How was your interaction with Doveoct.fi? Thanks in advance.
