[duker33]

PO says that mail doesn't work on prod.

dcp logs celery-mail-worker run on prod returns traceback:

seems it's version conflict: our celery uses too new version of kombu.

4.2.1 kombu's version uses new Transport class's field names
https://github.com/celery/kombu/blob/master/kombu/transport/base.py#L135

[duker33]

... and celery don't control versions during build
https://github.com/celery/celery/blob/master/setup.cfg#L21

[duker33]

celery released hotfix according to this issue.
http://www.celeryproject.org/news/celery-411-hot-fix-releaesd/

I'll try to reniew it for 4.2.0 version

[duker33]

fixed on prod

2h includes chat with PO, working with prod
