Hello Dovecot Community, I am using Dovecot 2.2.13-12~deb8u1 (Debian Jessie). separator = / listescape plugin is NOT active LAYOUT=fs is NOT active I would like to prohibit a creation of folders with dot "." in the names - so creation of a folder "foo.bar" should NOT be possible. Currently, when I create "foo.bar" in Outlook 2013 it will be created but won't be synchronised with the mail server - Outlook shows it as "foo.bar (Only this computer)". Ideally the user should receive an error message informing that "the folder foo.bar could not be created." Thank you for your help. Regards, Marek Grondecki

Hi, everyone, I'm trying to get email working on a server. Web servers I have some experience with, but this is new for me. On FreeBSD, with dovecot2 (2.2.27), when I try to check email, Thunderbird says: Sending of password for user xxx did not succeed.Mail server xxxresponded: Authentication failed. And on the server, in the mail log, there's a message: dovecot: pop3-login: Disconnected (user disabled) Any idea what I'm doing wrong? I didn't mean to disable any users. Thanks! Bob

I have not tried it at all. Was just an suggestion. You can try something like protocol lda { namespace archive { ... } } On 10.02.2017 14:12, Nick Lekkas wrote: > > Hi Aki > > > > Thanks for your answer .... > > What version of dovecot have you tried it ?

dovecot logout issues
by Rajesh M 10 Feb '17

10 Feb '17

hi we are using dovecot version 2.2.7 (config file given below) centos 6, qmail, vpopmail, mysql server configuration hex core processor, 16 gb ram 1 X 600 gb 15 k rpm for main drive and 2 X 2000 gb hdd for data (No raid) busy server with around 4000 email ids --- load is around 2 to 10 the issue is that SQUIRRELMAIL webmail users suddenly lose connection while they are working on the webmail. after logging in, if the user tries to open a mail then the interface gives error invalid user id or password. this happens on an extremely random basis. also htop always shows a few delayed processes of dovecot (shown as D) on top -- pop3 and imap dovecot logs do not show any login error when such a logout takes place. the said mailbox contained just around 30 emails and it is not related to the timeout plugin of squirrelmail either since the same webmail folders works on other servers of ours without any issues. webmail load slowly in general however when it works normally webmail is very fast and able to handle several 10 s of thousands of emails in the inbox. ram consumed is 2 - 5 gb during peak hours. rebooted server but issue not solved issue is present for the last around 1 month and was not present earlier. help required please. thanks rajesh settings as such # 2.2.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-431.29.2.el6.x86_64 x86_64 CentOS release 6.5 (Final) # NOTE:

Hello, It seems that I get several emails a week from this list in my spam folder. Usually because the DKIM signature fails. Has anyone else noticed this problem or is it just me? -- Steven mainor steve(a)degga.net

<3112B2DB02AA4C97871A9E3C19D6C9B8.MAI(a)ns1.24x7server.net> Content-Type: text/plain; charset="UTF-8" hi we are using dovecot version 2.2.7 (config file given below) centos 6, qmail, vpopmail, mysql server configuration hex core processor, 16 gb ram 1 X 600 gb 15 k rpm for main drive and 2 X 2000 gb hdd for data (No raid) busy server with around 4000 email ids --- load is around 2 to 10 the issue is that SQUIRRELMAIL webmail users suddenly lose connection while they are working on the webmail. after logging in, if the user tries to open a mail then the interface gives error invalid user id or password. this happens on an extremely random basis. also htop always shows a few delayed processes of dovecot (shown as D) on top -- pop3 and imap dovecot logs do not show any login error when such a logout takes place. the said mailbox contained just around 30 emails and it is not related to the timeout plugin of squirrelmail either since the same webmail folders works on other servers of ours without any issues. webmail load slowly in general however when it works normally webmail is very fast and able to handle several 10 s of thousands of emails in the inbox. ram consumed is 2 - 5 gb during peak hours. rebooted server but issue not solved issue is present for the last around 1 month and was not present earlier. help required please. thanks rajesh settings as such # 2.2.7:

Quota error for disabled namespace
by Riecken Jens 09 Feb '17

09 Feb '17

Hello, Some of our users use a dedicated archive mailbox, so we've setup an archive namespace for it, which is by default disabled. This namespace has its own quota which is defined by quota2* settings. Every time a user without archive authenticates, dsync kicks in, lmtp delivers a message or imap is used an Error message gets recorded: "imap(user1): Error: quota: Unknown namespace: Archive/" This happens about 441,756 times per hour - putting heavy load on the whole logging chain. In my opinion it makes sense suppressing quota error messages for disabled namespaces or flag it as debug messages. I'm thankful for every solution for this problem! Best regards Jens Environment: Dovecot Version 2.2.27 (c0f36b0) Red Hat Enterprise Linux Server release 7.3 (Maipo) Linux 3.10.0-514.6.1.el7.x86_64 doveadm user '*' |wc -l: 15946 Relevant configuration sections: namespace archive { disabled = yes hidden = no inbox = no list = yes location = maildir:/archive/%h/Archive mailbox "Auto Archive" { auto = subscribe special_use = \Archive } prefix = Archive/ separator = / subscriptions = no type = private } The archive gets enabled by the authentication backend: user_attrs = ou=home=/mail/%U$/%u,=uid=500,=gid=500,quota=quota_rule=*:bytes=%{ldap:quota},archiveDisabled=namespace/archive/disabled=%{ldap:archiveDisabled:yes} To ensure that the archive storage stays within sane boundaries there is a quota defined for the archive: plugin { acl = vfile:/etc/dovecot/global-acls:cache_secs=300 acl_shared_dict = proxy::acl mail_replica = tcp:mail-replica:12345 quota = maildir:User_quota quota2 = maildir:Archive_quota:ns=Archive/ quota2_rule = *:storage=10G quota_rule = *:storage=2G quota_rule2 = INBOX/Trash:storage=+10%% quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=90%% quota-warning 90 %u quota_warning3 = storage=85%% quota-warning 85 %u quota_warning4 = storage=80%% quota-warning 80 %u sieve = ~/.dovecot.sieve sieve_dir = ~/sieve }

Changes to userdb not picked up
