I use the following Dovecot configuration:
# Store METADATA information in a file dovecot-metadata in user's home
mail_attribute_dict = file:%h/dovecot-metadata
# enable metadata
protocol imap {
imap_metadata = yes
}
# add necessary plugins for Lua push notifications
mail_plugins = $mail_plugins mail_lua notify push_notification
push_notification_lua
# Lua notification script and URL of EGroupware push server
plugin {
push_notification_driver = lua:file=/etc/dovecot/dovecot-push.lua
push_lua_url =
https://Bearer:secret@boulder.egroupware.org/egroupware/push
}
The Lua script is available under
https://github.com/EGroupware/swoolepush/blob/master/doc/dovecot-push.lua
The whole Dovecot configurations is available under
https://github.com/EGroupware/build.opensuse.org/tree/master/server:eGroupWa...
Dovecot runs in a Ubuntu 20.04 based container and seems to use the
correct liblua5.3:
root@750978e5c0ee:/# dpkg -l|grep -i lua
ii dovecot-lua 2:2.3.15-1+ubuntu20.04 amd64
secure POP3/IMAP server - LUA support
ii liblua5.3-0:amd64 5.3.3-1.1ubuntu2 amd64 Shared
library for the Lua interpreter version 5.3
ii lua-json 1.3.4-2 all JSON decoder/encoder
for Lua
ii lua-lpeg:amd64 1.0.2-1 amd64 LPeg library for the
Lua language
ii lua-socket:amd64 3.0~rc1+git+ac3201d-4 amd64
TCP/UDP socket library for the Lua language
Everything was running fine with 2.3.13, have not tried with 2.3.14 yet.
Any ideas?
