[Mailman-Developers] Problems with mailman3 installation via bundler

[Take]

Hello,

I already posted details from my experiences with mailman3 to 
users-lists where Mark Sapiro suggested that I should post my questions 
to dev-list instead.

So, long story short, I installed mailman3 via bundler and can access 
both postorius and hyperkitty via web browser. Additionally I can both 
join and leave the list, access help via email etc, so installation 
seems to be in order.

However, I'm in a situation where posts I send don't end up on mailing 
list and replies end up shunted. On the log file I get this:

mailman.interfaces.address.InvalidEmailAddressError


On validate.py I added logging to see what seems to be the problem with 
address, to validate-function:

from distutils import log
log.error("Validating address -> " + email)
if not self.is_valid(email):
...

It appears that variable email is empty at that point, for some reason. 
I tried to search the problem via google but came up empty. At this 
point I'd be willing to say that I have encountered a bug, but I'm not 
competent enough with python to actually verify the situation.
