@twisted1919 I'm using v1.3.6.2. I've had issues when I tried to update to .4 as I posted earlier in this thread. So I thought of updating it after is stabilized. Thing is that emails are not dkim signed on .2 even if signing is enabled and verified sending domain is added. Ideally I should update to .4 and see if that clears the issue. But I don't want to do that if we're still on the process of collecting bug reports. Do you have any clue on what is happening or is it really the time to update to .4 (provided you patched the archive to fix the issues reported here) ?
