Claws-Mail doesn't start on FC28 because it can't find libnsl.so.1. A softlink to libnsl.so.2 fixes the issue.
It's probably better to install libnsl which provides libnsl.so.1 rather than creating a symlink to a different library version.
But for what it's worth, claws-mail starts up without libnsl installed for me. I've not used it before, so I clicked through the setup process and the app started without error. Perhaps it's a plugin which has the libnsl.so.1 dependency?
It would be good to find out if there's a package which is missing a dependency. Something like this might help turn up any plugin which needs libnsl.so.1:
ldd /usr/lib*/claws-mail/plugins/*.so | egrep 'libnsl.so.1|:$'
I'm not a claws-mail user, so I don't know if it stores plugins elsewhere. If so, you'd want to look in those locations as well.
