[bug#42899] [PATCH v4 0/8] Dovecot and pigeonhole improvements.

[Alexey Abramov]

Hi Guix,

I have been a happy user of dovecot+pigeonhole for a few weeks now. I am adding 
@guix-devel to give these changes more attention. dovecot-pigeonhole is already 
merged, Thank you Tobias.

The next step is to provide some common location where dovecot services can 
find plugins and their settings. I created /etc/dovecot/modules directory, 
which is actually a link to "/run/current-system/profile/lib/dovecot" and it is 
creating during the activation time. By doing this we can make sure, that all 
dovecot services, those which come with dovecot, can find extensions like 
sieve/managesieve and their extra settings.

I am using mbsync for my email synchronization. And use the following snippet 
for my IMAPAccount/IMAPStore.

--8<---------------cut here---------------start------------->8---
IMAPAccount current-user
    Host localhost
    User aabramov
    Tunnel /run/current-system/profile/libexec/dovecot/imap

IMAPStore current-user
    Account current-user
--8<---------------cut here---------------end--------------->8---

I noticed that when I run imap this way, it reads dovecot configuration, and if 
some global (dovecot) settings are defined below the service ones, I get a lot 
of warning message that they won't affect those, and I should move them above 
in order to make them work. That is why I changed the order of serialization.

I also added some extra settings to the configuration, but those are not for 
all the services. If you don't apply any values to them, they are still 
serialized to every service, hence services are crashing with a fatal error. I 
added a change that will prevent it.

I have rebased my changes and provide v4 series of patches.

Please let me know what you think.
