podop's Issues

Syntax errors on python 3.7

While working on Mailu/Mailu#680, in an attempt to make more common images, dovecot and postfix got upgraded to python 3.7. Upon running, I've seen the following error (same on both containers)

[tim@sky ~]$ docker logs 9c917cd8a4cc
Traceback (most recent call last):
  File "/start.py", line 12, in <module>
    from podop import run_server
  File "/usr/local/lib/python3.7/site-packages/podop/__init__.py", line 10, in <module>
    from podop import postfix, dovecot, table
  File "/usr/local/lib/python3.7/site-packages/podop/postfix.py", line 94
    return asyncio.async(self.process_request(name, key))
                       ^
SyntaxError: invalid syntax

Workaround for now is to use python 3.6 for all images.

Error 500 on alias lookup.

Version: 1.8
Custom setup with traefik proxy

It seems i'm getting a http 500 error on the alias lookup. This while the same e-mail can be used to login in the admin interface.
This ofcoarse causes all mail delivery to fail towards this account. The database for alias is also empty.
