kopano-spamd (8.6.2) is broken

@irreleph4nt said in kopano-spamd (8.6.2) is broken:

I am sorry for not being clear. When the announcement came out that 8.6.2 was ready, I compiled from the source code hosted on your stash. I hence „tagged“ my package as 8.6.2. Hope that makes sense :S

Ah, then you should have a closer look at the different branches and tags on stash. If you are building from master, then you have something that is based on the 8.6.80 tag. If you want to compile one of our releases you should look in the related release branch kc-8.6.x and there build the latest tag.

I assume to check with phyton2 I‘d have to re-compile core?

No, for the Python components this is afaik not necessary. We just set the shebang during packaging to match the correct pyhton version, so you’d just have to change it to something else.

What‘s spamd‘s purpose

Its a helper tool to export messages that users move into their junk email folder and that you then (with a separate script) feed as spam or ham to spamassassin (or your other preferred solution that is capable of learning from eml files).

I´m facing the same problem with a current nightly build (core-8.6.80.1055_0+156-Debian_9.0-amd64). I definitely don´t use python 3.x but python 2.7 instead.

Moving an email to junk leads to the following log:

I don’t really get that logic. Kopano supports python3 if I am not mistaken. I am using packages for Suse Leap and they are only provided for python3. I get the same issue as above but already since 8.6.0.
Is there a workaround?

cburghardt

So what I did is to edit kopano_spamd/init.py and to convert the searchkey to binary:
self.learnham and self.was_spam(b’searchkey’)
self.mark_spam(b’searchkey’)

Thanks for the hint!
I confirm, most of the error messages are gone, but not all:

this has been fixed for a month already (in https://stash.kopano.io/projects/KC/repos/kopanocore/commits/dc15ffc9334b228b54539796e175c9cf7fd24f46) you should update your version.

Thanks for the hint! Upgraded to build 1248 and added the two tweaks from cburghardt mentioned above.
Now I´m getting:

So still no luck, it´s getting frustrating.
Is there some wiki page or doc how to track such issues down?

Hi,

Upgraded to latest 8.6 (nightly) today, and have a similar problem.
In my case it seems like the item.header(self.headertag) fails into a NoneType object that does not support upper().
Get the following error whenever I move a message into the Junk folder:

2018-07-28 16:55:27,197 - spamd - ERROR - could not process change for entryid 000000003872FA2265094788A871E21E74BB150101000000050000004FE6C1B1D13743A0ABFB9AB828B4FCC100000000 ([SPropValue(0x67110003, 148806L), SPropValue(0x67150003, 134L), SPropValue(0x0FFA0102, ‘8r\xfa"e\tG\x88\xa8q\xe2\x1et\xbb\x15\x01’)]):

item.header(self.headertag).upper() != ‘YES’:
AttributeError: ‘NoneType’ object has no attribute ‘upper’

Update:
Removed “.upper()” from the script for testing, and got past this problem.
Obviously when the header does NOT contain “X-Spam-Flag”, an empty object is returned, hence it breaks the code here.
-Please update code to avoid this issue (e.g. test validity and default to “NO” if property is not found)

Second observation, amavis seems to almost be a requirement. -I’m using Spamassassin with clamav. -What should i set the sa-group to when amavis doesn’t exist?

hi all,

sorry for the problems you are having. I will take a look shortly at the mentioned issues.

the header problem, should be easy to solve
running spamd with python3, as now happens in master
the GetReceiveFolder issue

I wouldn’t use b’searchkey’, as this results in the literal word ‘searchkey’…

mark dufour

hi all,

quick update: I made a PR which should address above issues. it should land in master within a few days.

we now treat a missing header as signal the mail should be seen as spam
made some python3 fixes, and made sure our tests test spamd with python2 and python3
made store.inbox return None for public stores, avoiding the GetReceiveFolder issue

will post an update once this PR makes it through QA.

mark.

Hi Mark!
It´s really great to see progress here, after this was kind a dead end for some months.
Many thanks for taking care.

Small comment on the default handling if the spam tag is missing: Best option would be to have this configurable via the cfg file. While your proposal is obviously the best approach to be on the safe side, there are several spam solution besides amavis that only add the tag on spam emails and leave ham emails untouched.

Chris

let’s first check if everything is better now. the patches have been merged to our 8.7 branch. I will let you know once they hit master.
