Hello Voytek,

the *-devel packages include header files that are only needed if you want to compile something,
they are not needed for running a dovecot server. Likewise the *debuginfo packages, they contain
information that is helpful for debugging dovecot.

Your problem is here:

Error: Package: 2:dovecot-lua-2.3.4.1-1.x86_64 (dovecot-2.3-latest)
          Requires: dovecot = 2:2.3.4.1-1
          Available: 1:dovecot-2.2.36-3.el7.i686 (base)
              dovecot = 1:2.2.36-3.el7


If you want to install dovecot-lua-2.3.4.1-1.x86_64 you need dovecot 2.3.4.1-1
but the repository you configured has 2.2.36-3. Your output shows you're using
the base repository, which is from centos. Your are not using the dovecot repo.
Maybe you need to enable it - look for enabled=0 in /etc/yum.d/* files and change
to enabled=1 or stay with 2.2.36 from centos.

Best regards
Gerald

should I just go for "dovecot dovecot-mysql dovecot-pigeonhole" ??

tried :

yum install dovecot dovecot-devel dovecot-mysql dovecot-pigeonhole

and, it installed OK, I guess I don't really need the other ones ?
