I have untangle 14.2.2 in bridge mode. I was getting a lot (more) spam on my exchange server recently, so I installed / switched on the Spam module. I had it running for a week set to mark, and (as expected) messages started to appear with SPAM in the subject.
I changed from Mark to Quarantine today, and again, all seems ok and emails go into quarantine. However, the issue is, if from within quarantine I select Release to inbox (or Release to inbox & add sender to safe list) the emails never arrive on the exchange server (well, I think maybe 1 out of about 10 did). I have looked at the logs on the exchange server, and there doesn't seem to be any sign of the message trying to get delivered. I then looked at the /var/log/exim4/mainlog log on the unable server, and at the time I did the release of one of them I see the following (I have replaced my domain name with my.domain):

I have untangle set to "Send email using the specified SMTP Server" (but the same happens with it set to "Send email directly").
Clicking the Test email button works, and also getting the daily reports email works ok, so it seems something specific to releasing quarantine emails.
Anyone seen this before / have any ideas?
Thanks,
Ian.
