Bug TypeError: 'NoneType' object has no attribute

[katschingg]

I managed to install MacroMilter as a service under Debian.
Also added the milter using

postconf -e smtpd_milters=inet:127.0.0.1:3690 milter_default_action=accept

It seems to work but I sometimes get an error in the SystemLog which is:
Feb 22 17:02:35 srv python[1062]: Traceback (most recent call last):
Feb 22 17:02:35 srv python[1062]: File "/usr/local/lib/python2.7/dist-packages/Milter/__init__.py", line 666, in connect_callback

Feb 22 17:02:35 srv python: MacroMilter: milter claimed not to reply in state 2 but did anyway 3

The macromilter.log does not show any error (also not on DEBUG) so I guess the script exits before any log output and I cannot tell which email/input caused this.

It seems to be a problem with the hostaddr ip information. Can you reproduce the problem? What MacroMilter version are you using?

[katschingg]

Version:
2019-02-23 12:04:46 MacroMilter startup - Version 3.6

IP information:
Do you mean find out my own ip (127.0.0.1) or the ip address of the sender?

Just saw another message:
Feb 23 10:48:33 srv postfix/smtpd[28013]: warning: milter inet:127.0.0.1:3690: can't read SMFIC_DATA reply packet header: Success
But I guess that's not related?

It seams to be an error from the milter interface. It handovers a "empty" IP property within the milter object.
I have to debug and reproduce the error. What libmilter an pymilter version you are using?
