Hi Eric,

Just to confirm, did you leave it enabled in "mime digest" mode for longer than
a day so that there was list traffic to bundle and digest for you? I don't see any
errors in the error log related to MIME digest sends, but see about reproducing this today
and submit a bug.

Yes, I can confirm that I left mime digest on for several days and there were mails which I didn't receive. Note that regular digests aren't working for me, either. Currently the only working setting seems to be single mail delivery, which is not my preferred setting.

Did you manage to reproduce that?

The preference lookup appears to give precedence to the settings on the subscription, then
on the address, then on the user ("global"), and finally on the system
default—it stops at the first defined value it sees. I'll file a bug to have some
better clarification in the UI.

Great, thanks for the bug and the explanation!

Warm regards
Marco
