I'm confused, could you give the link to the project/mapping that needs to be deleted? (admins can do it)

ping ?

As far as I can see:

There is a sysconftool in pkgdb : https://admin.fedoraproject.org/pkgdb/package/sysconftool/ mapped in anitya https://release-monitoring.org/project/5763/

I cannot find a courier-mta package in pkgdb : https://admin.fedoraproject.org/pkgdb/packages/courier-mta*/ not in anitya https://release-monitoring.org/projects/search/?pattern=courier-mta*

However, there is a courier project in anitya: https://release-monitoring.org/project/4927/ that was mapped as corresponding to the courier package in Fedora (while this package does not exist).
So I dropped this mapping.

I hope this is what you had in mind.

Thanks

Yes, this is what I meant. Thank you.
