quota setup assistance (postfix+dovecot+mysql)
Hello list,
I have been struggling with establishing a working installation of dovecot with mySQL quota support. I have not been able to find a guide or tutorial that works for the current revisions of software I have at my disposal.
Most notably, the error I see in the mail log is as follows :Mar 23 00:55:31 host dovecot: lmtp(328): Debug: Module loaded: /usr/lib/dovecot/modules/lib10_quota_plugin.so Mar 23 00:55:31 host dovecot: lmtp(328): Error: dlopen(/usr/lib/dovecot/modules/lib11_imap_quota_plugin.so) failed: /usr/lib/dovecot/modules/lib11_imap_quota_plugin.so: undefined symbol: command_unregister Mar 23 00:55:31 host dovecot: lmtp(328): Fatal: Couldn't load required plugins
I have attached my dovecot -n output. The installed revision of dovecot is 2.2.9 on ubuntu 14.04.02 LTS.Thank you in advance.

The imap_quota plugin is relevant only under protocol imap {}. It reports quota usage via the IMAP protocol. Under lmtp and any other protocol that can change quota usage, you need to load only the quota plugin, which does the actual work of accounting and enforcing the quota.

Thank you for the hint. So what I need to do is remove $mail_plugins from each "mail_plugins =“ (I think the information I found was wrong in using $mail_plugins on each mail_plugins =, based on what you said above) , and only set the correct corresponding mail plugins? Is my example below, correct?e.g. :
protocol imap {
mail_plugins = zlib quota imap_quota imap_zlib antispam
}
protocol lmtp {
mail_plugins = zlib quota

Finally, doveadm is sort of a "protocol" too and any protocol for which you did not specify its own "mail_plugins = ..." will use the global value itself. So for example here you explicitly turned off all plugins for lda, overriding the global value. And doveadm will use the global value. So just take it all into consideration.

That makes sense. :)<snip>

I’m certain it is set.

Thank you for the tidbit. That is good to know.Here are the currently set parameters for mail_plugins in each config file :
10-mail.conf : mail_plugins = $mail_plugins zlib quota
15-lda.conf : mail_plugins = $mail_plugins sieve
20-imap.conf : mail_plugins = $mail_plugins imap_zlib imap_quota antispam
20-lmtp.conf : mail_plugins = $mail_plugins sieve

Doesn't make much sense. If that's the current config (and you restarted dovecot) then that shouldn't be happening. A good way to understand dovecot's config as it actually got applied is to run 'doveconf -n', try to review the output, and post here after masking out private info if you need further help.

It might be a operating permissions issue then. The file(s) exist but the permissions are root:root on /usr/lib/dovecot and everything below.
Does this mean I need to change the auth workers "user = " parameter? Some are set to mail and some to the virtual mail user (vmail).
Here are the dovecot packages I have installed :ii dovecot-antispam 2.0+20130822-2build1

Should I be using lmtp with postfix + mysql and dovecot? Or should I be using lda? The directions I read were for lmtp.--

The actual question is, why your system cannot load the shared libray lib11_imap_quota_plugin.so dynamically, although lib10_quota_plugin.so works.
Maybe you should remove the failed file and force a reinstall of the package. I don't suppose, the package is defective, someone other should have reported this problem by now.

This problem can be reproduced in one second. Here you go:
protocol lmtp { mail_plugins = $mail_plugins sieve imap_quota }

Simple: imap_quota is not a plugin for lmtp, it is a plugin for imap. Notice the last bit of the error message. It won't work just like you couldn't dynamically load it into LibreOffice or whatever.

This problem can be reproduced in one second. Here you go:
protocol lmtp { mail_plugins = $mail_plugins sieve imap_quota }

Thank you for pinpointing the issue. Unfortunately, I am at a lost then as to why it fails for me. My settings are as follows :10-mail.conf : mail_plugins = $mail_plugins zlib quota
15-lda.conf : mail_plugins = $mail_plugins sieve
20-imap.conf : mail_plugins = $mail_plugins imap_zlib imap_quota antispam
20-lmtp.conf : mail_plugins = $mail_plugins sieve
Am I to remove each $mail_plugins and then explicitly set each mail_plugins = ""? Looking at my doveconf -n file I posted originally, I do see the following :protocol lmtp { mail_plugins = " zlib quota imap_zlib imap_quota antispam sieve" }
And checking the doveconf - n output right now on the server I see the same as above (I was checking in case I had attempted changes since my original post, but nothing has changed).
So, either due to a bug or working as intended (or possibly, both), my lmtp protocol section is loading all $mail_plugins.
Is it correct to theorize that if the file 20-lmtp.conf were to be renamed so that it was numbered between 16 and 19, that this $mail_plugins problem would be resolved? Or should I rename 20-imap.conf and 20-pop3.conf (I have not enabled POP3 as of yet), to higher digits (e.g. : 21-imap.conf and 21-pop3.conf)? If renaming the conf files to higher digits will fix this for me, I am inclined to do so to the imap and pop3 conf files. :)
If this is a bug, is this the ubuntu package at fault, or something further up the chain?--

The order in which the config files are included and parsed ought not to matter. Dovecot parses the entire config, resulting in what you see in doveconf -n output, before it does anything. Only the final result applies.
If your config file says:
key = value1 key = value1 value2 (or, key = $key value2 - same thing)
Then key = value1 value2, and that and only that ever matters.
I have a suspicion as to what your issue is.
Here is a clarification. Dovecot has only one single config file - the result of concatenating all files as included out of the dovecot.conf file. The names of the individual files in conf.d are technically meaningless. The config is organized into topics only to make it easier to humans to find their way around.
The way to apply a setting to a specific component is to put it under a section such as: protocol imap {}. You've mentioned that you have different mail_plugins settings in different _files_, but are you sure they are always inside the protocl xxx {} section?

Thank you for this detail. While I suspected such operation, I now know for sure.
While not all protocol sections are defined in each file, here are the contents of the other files that contain mail_plugins parameters :10-mail.conf: mail_plugins = $mail_plugins zlib quota
20-imap.conf: mail_plugins = $mail_plugins imap_zlib imap_quota antispam
And here are the contents of each defined protocol section :15-lda.conf: protocol lda { 15-lda.conf: mail_plugins = $mail_plugins sieve 15-lda.conf: }
20-lmtp.conf: protocol lmtp { 20-lmtp.conf: mail_plugins = $mail_plugins sieve 20-lmtp.conf: }
Given that doveconf -n shows :protocol lmtp { mail_plugins = " zlib quota imap_zlib imap_quota antispam sieve" }
I need to change something, somewhere. I am not opposed to removing $mail_plugins from any protocol section. Is it syntactically correct to use $mail_plugins in the 10-mail.conf file? Perhaps this is my source of the issues for lmtp?
Here are the results of my tests when making changes :test 1 )
- removed $mail_plugins
10-mail.conf: mail_plugins = zlib quota
- doveconf - n output shows :
mail_plugins = zlib quota imap_zlib imap_quota antispam protocol lmtp { mail_plugins = zlib quota imap_zlib imap_quota antispam sieve }
test 2 )
- removed mail_plugins from 10-mail.conf
- doveconf - n output shows :
mail_plugins = " imap_zlib imap_quota antispam" protocol lmtp { mail_plugins = " imap_zlib imap_quota antispam sieve" }
test 3 )
- removed mail_plugins from 10-mail.conf
- removed $mail_plugins from 15-lda.conf, 20-imap.conf, and 20-lmtp.conf
- explicitly set mail_plugins in 15-lda.conf, 20-imap.conf, and 20-lmtp.conf
- doveconf - n output shows :
mail_plugins = zlib quota imap_zlib imap_quota antispam protocol lmtp { mail_plugins = zlib quota sieve }
I’m curious as to why on the 2nd test, there are quote marks in the mail_plugins parameters but not in the 1st or 3rd test?
I think the 3rd test is the desired operating configuration. If so, why is using $mail_plugins causing an issue? Is this a bug in the ubuntu 14.04 packages? Or was I wrong to use $mail_plugins in the lmtp protocol section (if so, the same is likely true for the lda protocol section)?--

When you use $mail_plugins for the first time, it is equal to the empty string, because it wasn't set yet. When you set a config setting to $mail_plugins followed by a space, and

Is this a bug in the ubuntu 14.04 packages? No. Or was I wrong to use $mail_plugins in the lmtp protocol section No.
You need to revise your general understanding of how dovecot configuration works. I suggest you read slowly and carefully my previous messages in this thread, as I have already explained a few facts that are relevant to your trouble, plus whatever other sources, such as the dovecot wiki.
