      The OOF issue appears to remain with kopano-dagent 11.0.0.

        Hello lantz.

        Could you let me know if you have changed the tmp path of the dagent via the following config:

        tmp_path = your_new_path
        Or, if you set an env variable under TMP or TEMP?

        If so, could you provide me the full path you set?

          Hello Solidus

          Many thanks for considering my findings.

          The tmp path was not internationally changed and it appears not to be changed in the test system in question.

          Since I test kopano-dagent in a docker environment you should be able to reproduce the issue by following the procedure below:

          git clone https://github.com/mlan/docker-kopano.git
cd docker-kopano/demo
make init
make app-test_lmtp
make app-test_oof1
make app-test_lmtp
make app-test_oof0
make app-test_lmtp
make app-logs
make app-env
make app-sh

              Please accept the following additional piece of information.

              It is likely that whatever causes the issue described here was introduced after the 9th of October 2020, since OOF works just fine (in the docker environment mentioned above) using the nightly builds that was available on that date.

                @lantz Hello lantz.

                Thanks for the extra information. I am working on reproducing your issue and will update when I have news.

                Thanks.

                  Hello again @lantz :)

                  I have found the issue and fixed it. As soon as the PR is merged, it should be available in a nightly build. I’ll let you know once that happens. FYI, this’ll also likely be back-ported to version 10.

                  Thanks for reporting the issue!

                    @lantz The fix has been merged to master. Tomorrow’s build should have it, let me know if you are still facing issues with this.
