pyDNS dependency?

[robertlagrant]

I'm trying to install on Python 3 on Windows (the least-likely-to-work combination) and while passlib installed fine, it borked on pyDNS. I'm just wondering what that dependency is for, since the only time I see it when I search the repo is in the setup.py file.

Can it be safely removed?

Update: it installed fine from https://github.com/robertlagrant/pyramid_simpleauth, where I removed that dep. Will see what happens.

Might be something to do with the email validator, which I think has a resolve dns option?

[matthewblain]

it looks like PyDNS offers a module named 'DNS', which is not referenced anywhere in the simpleauth source code. can this be fixed, since it's apparently not used?
email validation appears to be done using formencode which in turn appears to use dnspython (not PyDNS), but it also does not require it--it will fail the import, issue a warning, and keep going.
