Bad performance experiences with dbmail 2.x were the main reason why we migrated to dovecot. If you've got a MySQL database with 80 GB of binary chunks then things are getting ugly, especially when it comes to efficient backup and restore of whole mailboxes or single e-mails. The SQL backend (and the IMAP user experience) becomes very slow if the database does not fit completely into RAM. There are many performance improvements and bug fixes in dbmail 3.x, but instead of evaluating then, we decided to migrate to Dovecot. One should think twice, or even three times about how to design an efficient SQL backend for a good user experience. Regards Daniel -- https://plus.google.com/103021802792276734820

[Dovecot] doveadm quota get -A via doveadm-proxy director with LDAP
Hi,
We are running Dovecot 2.1.10
I want configure dovecot to do execute doveadm commands on the proxy server.
We have 1 proxy with director and 2 mail servers. we use LDAP
when I try to do doveadm quota get -u user it works fine.
The problem is when I try to do doveadm quota get -A ON PROXY
I have this result:
doveadm(first_user): Error: Proxy is missing destination host
doveadm: Error: Failed to iterate through some users
Username Quota name Type Value Limit
%
in 10-auth.conf I have "!include auth-ldap.conf.ext"
in auth-ldap.conf.ext I hve:
passdb {
driver = ldap
args = /etc/dovecot/dovecot-ldap.conf.ext
}
userdb {
driver = ldap
args = /etc/dovecot/dovecot-ldap.conf.ext
}
and In dovecot-ldap.conf.ext I have:
uris = ldap://ldap:port
dn = x
dnpass = y
auth_bind = no
ldap_version = 3
base =base
scope = subtree
user_attrs = attributes
user_filter = (mail=%u)
pass_attrs = userPassword=password,uid=user=%L$,cn=proxy,=starttls=any-cert
pass_filter = (mail=%u)
iterate_attrs = uid=user
iterate_filter = (uid=*)
I don't know where is my error!!!
Thanks in advance

[Dovecot] Sieve puts incoming message into inbox on any problem with submission_host
Hello dovecot-users, I have a question/suggestion regarding the submission_host feature of the lda (either via dovecot-lda binary or lmtp) in combination with sieve. When trying to deliver message to a mailbox and this message has a sieve redirect action applied to it, dovecot is using the configured smtp server to forward the message just fine. Unfortunately, if the server configured for submission is unavailable, returns an error or cannot be found via DNS, sieve will simply put the message into the inbox and be done with it: --- dovecot.log --- dovecot: lda(user1): Error: lmtp client: DNS lookup of idonotexist.example.com failed: Name or service not known dovecot: lda(user1): Error: sieve: msgid=unspecified: failed to redirect message to (refer to server log for more information) dovecot: lda(user1): sieve: msgid=unspecified: stored mail into mailbox 'INBOX' dovecot: lda(user1): Error: sieve: execution of script /mailboxes/user1/.dovecot.sieve failed, but implicit keep was successful (user logfile /mailboxes/user1/.dovecot.sieve.log may reveal additional details) --- /dovecot.log --- The same applies to vacation messages being sent out. Especially with an (unconditional) redirect action, users don't expect to find messages in their inbox. Also problems with the submission_host could very much be temporary and a little delay in delivering a message is better then putting it somewhere the user doesn't expect a message to be. Is there any way to change the behavior of dovecot or the sieve plugin to tempfail in case a message cannot be sent out? I know that with multiple sieve actions it gets more complicated as there could be corner cases were the first message can be sent via the submission server and another message produced by the same sieve script cannot. I'd love sieve to behave like this: a) if submission host is unreachable (hostname wrong, timeout, ...) -> tempfail b) if submission host returns 4xx error -> tempfail c) if submission host returns 5xx error -> fail(-save) and just drop the message into inbox or even have an option to reject the message completely in this case. In case of a tempfail response, the mta simply queues the message and tries again later. In case of a permanent fail the mta will create a bounce message to in form the sender. Regards and have a great weekend, Christian
[Dovecot] quota recalc does not work
Hi
I upgraded dovecot from 2.0 to 2.1 , and now i face the quota recalc
problem.
All settings are keep in mysql
Before , after a change in mailbox.quota field, i run doveadm quota
recalc and all was ok ,
but now that command doesn't do anything.
After i change a quota for a user , i have to restart dovecot to get the
new quota ,
or do a "doveadm reload" instead of recalc.
And the doveadm quota recalc -A" give me back a lot of
"doveadm(username): Info: User no longer exists, skipping"
Any thoughts ?

Re: [Dovecot] Mails don't get deleted after POP3 [SOLVED]
Hi, there! > I guess that dovecot cannot write to some files / has problems > with write permissions. But it doesn't tell me anything... The reason was indeed that dovecot couldn't write to /var/mail I had to chown it to the mail group as it says in: mail_privileged_group: mail Thank you, Regards, Rob Am 08.11.2012 22:21, schrieb culli...@rocketmail.com: Hi, there! Well, I am new to dovecot, so please be patient with me: I have a virtual server and want to setup simple mail delivery. postfix, saslauthd and dovecot basically work fine. The only open issue is, that (I guess) dovecot doesn't remove the mail when it's retrieved via pop3 from the server. It keeps sending me the same emails again and again. (The mail client (Thunderbird) is configured to remove the messages from the server - it was working already.) I guess that dovecot cannot write to some files / has problems with write permissions. But it doesn't tell me anything... Can you tell me, what configuration might be wrong or how can I enable more debugging to see what dovecot is doing after the mails got sent out via pop3?
