try: yum clean all

Gerald , thank you

it shows in the output after 'second step' below:

# yum clean all
Loaded plugins: fastestmirror, langpacks, priorities
Cleaning repos: base centos-sclo-rh centos-sclo-sclo dovecot-2.3-latest epel
             : extras gf remi-safe updates
Cleaning up list of fastest mirrors
Other repos take up 622 k of disk space (use --verbose for details)

this deletes all cached data, then search for dovecot:

[root@noc ~]# yum search dovecot --showduplicates

...

-> base, epel, extras, updates are the repositories that are queried -
this is the name in [] brackets from /etc/yum.repos.d/*.repo -> you should
see dovecot-2.3-latest there

should I try 'yum install ...' again ?
