Double checked spelling this time…
I can not find the Source package of rspamd in the nethserver package repository nor a SPEC file on github…
BTW: (in package repo)
Did you need to build a custom ragel for rspamd?
https://www.rspamd.com/downloads.html (build rspamd tab)
ragel - state machine compiler. Please be aware that the experimental version of Ragel (namely, 7.0) is NOT compatible with Rspamd. Since it is shipped with CentOS 7.0, there is no way to use Ragel from the packages and you need to build compatible Ragel (e.g. 6.8) manually from the source packages or from source code. Ragel is required to build Rspamd not to run it.
