[ckan-dev] ckan mailer problem

Mon Nov 28 11:04:47 UTC 2016

Hi Hildegard,

this sound like a good suggestion, and it seems you already spent quite
some time digging in the code. Maybe you could create a Pull Request on
GitHub, so this could be discussed on a code level?
This would make it a lot easier to follow all the changes and see the
dependencies to other modules/eariler version etc.

What do you think?

Best regards Stefan
