Permissions problem with mdbox maildir
by Emanuel Evans 24 Feb '15

24 Feb '15

Hi! Apologies if this has come up before, or if this is a duplicate posting (I tried posting before but I think it got lost). Anyways, I'm trying to set up an IMAP server with dovecot, and everything seems to be more or less working except that I periodically see error messages like this in my logs: Feb 18 01:01:15 stark dovecot: lmtp(31956, root(a)aleme.nu) Error: link(/var/decrypted/vmail/aleme.nu/root/mailboxes/INBOX/dbox-Mails/dovecot.index, /var/decrypted/vmail/aleme.nu/root/mailboxes/INBOX/dbox-Mails/dovecot.index.backup.tmp) failed: Operation not permitted I'm assuming it's a permissions problem with my maildir, but I can't figure out what the relevant process is in order to fix it. The maildir is owned by vmail with permissions set to 700; here is the output of dovecot -n: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.8 fuse.encfs mail_gid = vmail mail_location = mdbox:/var/decrypted/vmail/%d/%n mail_uid = vmail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave 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 = } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { antispam_allow_append_to_spam = no antispam_dspam_args = --user;root;deliver=;--source=error;--client antispam_spam = Junk antispam_trash = Trash sieve = ~/.dovecot.sieve sieve_before = /var/lib/dovecot/sieve/before sieve_dir = ~/sieve sieve_global_dir = /var/lib/dovecot/sieve/global } protocols = " imap lmtp sieve" 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 } service_count = 1 } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } user = vmail } ... <ssl stuff> ... userdb { args = uid=vmail gid=vmail home=/var/vmail/%d/%n driver = static } protocol lmtp { mail_plugins = " sieve" } protocol imap { mail_plugins = " antispam" } As you can see, I'm keeping the maildir on an encfs-encrypted volume, in case that's relevant. Please let me know any ideas for why this might be happening. Thanks in advance! Emanuel

[Dovecot] Sieve vacation not working
by Phill Edwards 24 Feb '15

24 Feb '15

I've been trying all night to get vacation working in my .dovecot.sieve file. The way our email works is we have one account on dovecot which serves my mail and my wife's and we use procmail and sieve to put the emails in different folders depending on who it's for. I'm trying to set up a vacation reply on my wife's email address (aaaaaaaa@optus* below) so people can update to her new address. Here's my file with the email addresses masked: require ["fileinto", "vacation"]; if address :is "to" "xxxxxxxxxxxxxxx(a)ozemail.com.au" { fileinto "Phill_OzEmail_Folder"; stop; } elsif address :is "to" "yyyyyyyyyyyyyyyyy(a)optusnet.com.au" { fileinto "Phill_Optus_Folder"; stop; } elsif address :matches "to" "aaaaaaaa@optus*" { vacation "Please update my email address to bbbbbbbbb(a)exemail.com.au"; fileinto "Sarah_Optus_Folder"; stop; } else { keep; stop; } The problem I'm having is that no auto-replies are sent. I removed .dovecot.lda-dupes and that didn't help; so then I touched it and now it's a 0 byte file and that didn't help. There is no dovecot.sieve.err file and I can't see anything in /var/log/dovecot.log which gives any message about why this wouldn't work. The emails to aaaaaaa@optus* get filed into the right folder so I know the matching is working. I've also tried a reject recipe and that worked fine, so I know that it can send an email if it chooses to. So it's a complete black box mystery as to why it just won't send a reply. Regards, Phill

Using Dovecot IMAPC to collect mail
by Иван Колосов 23 Feb '15

23 Feb '15

Hi list. I was looking at Dovecot's imapc feature for some time. I am aiming to use Dovecot with imapc as a kind of "store-and-forward" proxy. If I understand imapc correctly, there are two connections at work — one between the client and Dovecot and one between Dovecot and backend. When the client asks Dovecot for mail, Dovecot will retrieve mail from the backend and then send it to the client. So the question is, is it possible to configure Dovecot with imapc in such a way that it would store the mail it passes to the client? Should I use mail filter plugin to do this? I am also quite confused about authentication in this setting. Let's assume we use 'plain' authentication mechanism, then what happens? I guess that the client just sends Dovecot its credentials, and Dovecot tries to authenticate with them at the backed, responding to the client accordingly. Is this true? Thanks.

Dovecot Director Issue/Bug when host=""
by Julian De Marchi 20 Feb '15

20 Feb '15

heya-- Been playing with dovecot today as I was learning about the features I haven't used yet like the director/proxy stuff. I setup a basic dovecot stack today which is 1 director and 1 IMAP dovecot server behind it. I have one user setup in MySQL and when I first changed from proxy mode to director mode I left the host column populated with the IMAP server. Once I confirmed this was working I then changed host to "" not NULL. When I then preformed my next check I got these errors(no details omitted as this is a test system): Feb 20 14:57:19 smtp-test dovecot: auth-worker(15423): Debug: sql(email3(a)example.com,10.107.0.8): query: SELECT email as user, password, host, 'Y' AS proxy_maybe, 'user' AS master, 'password' AS pass, 'any-cert' AS 'ssl' FROM virtual_users WHERE email='email3(a)example.com'; Feb 20 14:57:19 smtp-test dovecot: auth: Error: proxy(email3(a)example.com,10.107.0.8,<Zz0b430PigAKawAI>): DNS lookup for failed: Invalid input from dns-client Feb 20 14:57:19 smtp-test dovecot: auth: Error: close((null)) failed: Bad file descriptor When I changed the host data from "" to NULL all worked as expected. So the question is: is this a bug with the error output? It was kind of hard for me to diagnose at first without leaning on support in the freenode channel. This is very repeatable as it is a proper error, you can't resolve "". --julian

Xi autobuilds restored
by Stephan Bosch 19 Feb '15

19 Feb '15

Hi, Xi had problems for more than a month now. I finally managed to access it yesterday, but it was a bit more broken than I anticipated. I had to re-install the whole system. It should now work as before. It is now Debian stable/amd64, so that is now also the master release, which is always built first. Regards, Stephan.

Re: lazy_expunge + mdbox
by fernando.figaro＠uol.com.br 19 Feb '15

19 Feb '15

It appears to me that this issue is related to how lazy_expunge and last_instance work with mdbox - that is different from maildir. With maildir, the message is moved to the expunged namespace only when the last copy is removed (example: from trash folder). With mdbox, first time when you move message from one folder to another, dovecot creates a copy in the expunge namespace. When you delete messages or expunge them from Trash folder (example, nightly 'doveadm expunge' cronjob) they are simply deleted because they already have copies at expunged namespace. @Timo, is that correct ? This is what I could understand from my tests. Thanks, Fernando De: fernando.figaro(a)uol.com.br Enviada: Quarta-feira, 4 de Fevereiro de 2015 23:15 Para: dovecot(a)dovecot.org Assunto: lazy_expunge + mdbox Hi, I'm studying an issue related to mdbox and lazy_expunge. If it is active in the imap configuration, when you delete a message (copy to new folder + expunge old folder), a copy is also sent to the expunge namespace. I realize that is something related to mdbox and lazy_expunge_only_last_instance and found almost no references except this one (http://hg.dovecot.org/dovecot-2.2/file/24d6708cea76/TODO) lazy_expunge_only_last_instance=yes + mdbox doesn't work, because refcounts don't update immediately One other suggestion I found was to disable 'move' capability. Does anyone has other news regarding this issue ? Thanks, Fernando
