performance issue with UID SEARCH
by Ben Burke 27 Feb '19

27 Feb '19

Hi, I'm running dovecot 2.2.x and I'm having an issue where I see many dovecot processes use all the available IO on a server. According to iotop the worst offenders seem to be in this state (NOTE: I swapped in phony username & IP info): dovecot/imap [someusername 123.456.789.012 UID SEARCH] The server in question is running with Maildirs on top of an XFS filesystem. Is there anything I can do to optimize "UID SEARCH" or find out why it's being a problem? I've read https://wiki2.dovecot.org/PerformanceTuning and the linked pages. By "being a problem" I mean iostat -xmt 1 /dev/diskdevice shows 100% utilization for long periods and in some cases io service times are taking many seconds... which causes thunderbird to timeout when doing things like appending messages to user "Sent" mailboxes. Any ideas? Thanks, Ben Burke

new Centos server install yum dependancy error

I'm installing a new Centos 7 server, following repo.dovecot.org/ page, but, get this: (I've opted to install all BUT pgsql (use mysql), not sure I really need all other packages..?) should I just go for "dovecot dovecot-mysql dovecot-pigeonhole" ?? tried # yum install dovecot dovecot-debuginfo dovecot-devel dovecot-imaptest dovecot-imaptest-debuginfo dovecot-lua dovecot-mysql dovecot-pigeonhole dovecot-pigeonhole-debuginfo dovecot-pigeonhole-devel ... --> Finished Dependency Resolution Error: Package: 2:dovecot-lua-2.3.4.1-1.x86_64 (dovecot-2.3-latest) Requires: dovecot = 2:2.3.4.1-1 Available: 1:dovecot-2.2.36-3.el7.i686 (base) dovecot = 1:2.2.36-3.el7 Error: Package: 2:dovecot-pigeonhole-devel-2.3.4.1-1.x86_64 (dovecot-2.3-latest) Requires: dovecot-pigeonhole = 2:2.3.4.1-1 Installing: 1:dovecot-pigeonhole-2.2.36-3.el7.x86_64 (base) dovecot-pigeonhole = 1:2.2.36-3.el7 Error: Package: 2:dovecot-imaptest-2.3.4.1-1.x86_64 (dovecot-2.3-latest) Requires: dovecot = 2:2.3.4.1-1 Available: 1:dovecot-2.2.36-3.el7.i686 (base) dovecot = 1:2.2.36-3.el7 You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest -- Voytek

Removing a mailbox from a dovecot cluster
by Francis 26 Feb '19

26 Feb '19

Hello, How should I remove a mailbox from a dovecot cluster? I have two dovecot in a cluster. I tried to remove one user's mailbox with theses commands I found with a little google search: doveadm flags add -u user(a)domain.tld "\\Deleted" ALL doveadm expunge -u user(a)domain.tld mailbox "*" DELETED doveadm purge -u user(a)domain.tld rm -fr /var/vmail/domains/domain.tld/user If I do theses commands in a script (so one command after one, very quick), the data just keep coming back from the other server in the cluster (I suppose this is what's happening). If I do theses commands manually, so more slowly, the mailbox is created again but empty this time. If I connect from an IMAP client, I see an empty mailbox. Same thing if I connect an IMAP client to the second server from the cluster. But I still see the data in the storage (mdbox) of the second server (the "m.#" files are still there an they waste space on disks). I tried to do a "doveadm purge" on the second server, but it did nothing more, the data is still keep on the disks. I'm running dovecot 2.2.33.2 on ubuntu 18.04 on both servers. Thanks! -- Francis

Virus scan + removal on a mdbox mail storage
by Christoph Haas 26 Feb '19

26 Feb '19

Hi, I need advice on how virus scan and removal can be done on a _mdbox_ mail storage? On a maildir storage the virus scanner (e.g. clamav etc.) can detect and remove a email that is infected, since every email and attachment are stored in separate files. But in mdbox the emails and attachments are compressed together in one ore more mdbox-files ... I am anxious to convert my mail storage for virus scanning into maildir format, since I don't know if a virus or crypto trojan con be activated with this converting action =:-o Cheers Christoph. -- Christoph Haas

Linking mailboxes

25 Feb '19

Hi, I am new to Dovecot and I am trying to link an email account folder to another Maildir(its a backup of the older email). I want the email account to be able to access the older emails. I am assuming this is done by creating a symlink? Currently reading instructions on this page:- https://wiki.dovecot.org/SharedMailboxes/Symlinks At the moment I have the folder:- /var/mail/vhosts/example.com/email1/Maildir/.INBOX.newfolder Inside the folder:- drwx------. 2 vmail vmail 4096 Feb 23 13:39 cur -rw-------. 1 vmail vmail 232 Feb 23 13:43 dovecot.index.log -rw-------. 1 vmail vmail 51 Feb 23 13:43 dovecot-uidlist -rw-------. 1 vmail vmail 0 Feb 23 13:39 maildirfolder drwx------. 2 vmail vmail 4096 Feb 23 13:39 new lrwxrwxrwx. 1 root root 45 Feb 23 13:46 Other -> /run/media/computer/Storage/Email/mail/Other drwx------. 2 vmail vmail 4096 Feb 23 13:39 tmp lrwxrwxrwx. 1 root root 5 Feb 23 13:46 Users -> Users I am not able to access the folders in the Other folder structure(inside other there are other email inboxes ie(email1@example.com,email2@example.com,etc.). I want to get access to all the email subfolders. Could someone here advise how to do this or point me to some tutorials for this. Sincere apologies for this and many thanks in advance for helping...

Corrupted transaction log and redownloading
by azurit＠pobox.sk 25 Feb '19

25 Feb '19

Hi, today we had to hard-reboot one of our dovecot proxy backends and after boot up, lot's of accounts were showing this error and appeard empty: Error: Corrupted transaction log file ... After deleting the indexes (not uid file, problem wasn't in deleting indexes, i'm doing this often), e-mails showed up ok but e-mail clinets started to download them again. Why this happened and how to prevent it (other than 'not hard-rebooting')? I know that reboot could cause corruption of uid files in some cases but this time it looks like this was caused by corrupted indexes - how index corruption can cause redownloading and why? Thanks for any info. azur

password protected ssl key seems unsupported after update to 2.3.4.1
by admin＠f-hamelin.fr 25 Feb '19

25 Feb '19

Hi, On a debian server after an update to dovecot to 2.3.4.1 imaps mail client stop working. I’ve applied necessary migration for ssl_dh (cf https://wiki.dovecot.org/Upgrading/2.3 <https://wiki.dovecot.org/Upgrading/2.3> ) but that was not enough. The workaround I’ve setup was to remove password protection from the ssl_key file. All tests with ssl_key_password parameter failled (direct password, <path-file-with-password) searching I’ve found a message reporting a problem with that parameter and Stephan said it was tracked internally as DOP-851 Hope this will help.

permission denied errors with INDEX=MEMORY and trees plugin
by John McKay 24 Feb '19

24 Feb '19

I am using the trees[1] plugin to encrypt the mail on my disk. Because I don't want it to store any metadata in plaintext, I've also set INDEX=MEMORY in my mail_location configuration. However, whenever I get new mail I get errors like the following showing up in the journal: lmtp(john(a)octet.space)<21780><QDkrBqTXclwUVQAAQHGRUQ>: Error: Mailbox INBOX: Saving mail: read(/var/vmail/octet.space/john/Maildir/tmp/1551030180.M508113P21780.toaster.octet.space) failed: Permission denied (read reason=header Subject (Cache file is unusable)) It's like it's trying to read the message after it's been delivered, but is not able to because it's been encrypted. I seem to be able to get email just fine despite the error message. This happens both if I deliver mail using dovecot-lda or lmtp. Is there any way to fix this or at the very least suppress the error message? I have included my dovecot configuration below.
