To take another example, the thread 'What is /run/user/<user-id> directory and how to make sure it's created?' has just seen three new posts appear, those from 25/01/15 at 03:18 from Carlos and two nested posts many hours later, yet I've been checking the account throughout 25/01 and only a few dribs and drabs of other posts were appearing all day.
Unless I've been added to some filter by either the list maintainer, my French ISP or GCHQ, I'll have to consider it more likely the mail provider at fault. If it continues more than a few more days I'll look into it some more.
Just hit ctrl-U in Thunderbird while displaying one of the delayed emails. Look from the top-down at the lines that start with "Received:". They have a format like: Received: from PREVIOUS_STEP_SERVER ... by CURRENT_STEP_SERVER ...; some_date and some more text in between. The format varies depending on what software wrote each entry. So that they form a chain: Received: from SERVER_C ... by SERVER_D some_date Received: from SERVER_B ... by SERVER_C some_date Received: from SERVER_A ... by SERVER_B some_date So that you can see when it went out of the writer, when it entered suse, when it went out, when it reached your ISP, and possibly when you retrieved it. Everything is timestamped. You can determine precisely where the mail got stuck. It is easy. Just be mindful of timezones. Nowdays computers keep good clock time, so this is more reliable than it was. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
