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)?--
