I set up GMG on a new site running postfix smtp server with ​postgrey greylisting. When GMG sends a verification email to a new user@domain address, the email is greylisted by my local smtp server and GMG throws an error. The accounts are created fine (they can still log in), and after waiting the requisite time for greylisting, my GMG instance can successfully email these addresses.

I've marked this as minor, as anyone who does encounter this will likely have configured greylisting on purpose and should be able to figure out how to fix it. However, it would be neat if GMG were aware of greylisting and had a slightly smarter behaviour. Perhaps instead of defaulting to a yeowch page, it could display a message such as "account was created but email could not be sent."

Logs follow with identifiable information scrubbed.

git cloned master a few minutes ago.

setup.py depends on wtforms without specifying version. So I used 1.0.1, the most common wtforms version found (e.g. on Ubuntu 14.04 released 4 months ago).

Error follows.

On wtforms 1.0.1 there is only wtforms.validators.Required.

Either change code to stay with wtforms 1.0.1 (most commonly found),

or be explicit that this version is not acceptable in setup.py - wtforms 2 seems have this class.
