Hi.

The NixOS distribution for Dovecot uses a patch that hardcodes the path to the plugins in /etc/dovecot/modules. The modules themselves are located at /nix/store/z9kf4ri8sq9f3r510qsm59g1n6kfc7q6-dovecot-2.3.21.1/lib/dovecot, the script creates symlinks in the /etc/dovecot/modules directory. The additional modules are loaded normally.

Now I want to remove the patch. I added the parameter “--with-moduledir=$(out)/etc/dovecot/modules”, and the modules are located at path /nix/store/wb885d6w5dfchg9v481f55zj4a2p3r89-dovecot-2.3.21.1/etc/dovecot/modules. In the configuration I added the parameter `mail_plugin_dir

/etc/dovecot/modules`. The main modules load fine, but the optional modules don't want to load:

Error: 
Plugin 
'imap_sieve' 
not 
found 
from 
directory 
/nix/store/wb885d6w5dfchg9v481f55zj4a2p3r89-dovecot-2.3.21.1/etc/dovecot/modules

For additional modules, the mail_plugin_dir parameter is ignored.

Temporary solution

in src/config/config-parser.h file I replaced the line

#define 
CONFIG_MODULE_DIR 
MODULEDIR"/settings”

by

#define 
CONFIG_MODULE_DIR 
“/etc/dovecot/modules/settings”
