Anyone know who to contact to investigate? [*] I've got E-Mail delays so large that I manually crafted In-Reply-To etc. to reply to this :) I'm 99% sure it's some weird thing at GMail, and nothing to do with kernel.org. When I've experienced delays (sometimes of half a day or more) both https://public-inbox.org/git/ and https://lore.kernel.org/git/ have been updated. Konstantin Ryabitsev notes (and would be in a position to know) that GMail throttles delivery (with an smtp 451 error?). But the other day when Junio sent out a What's Cooking and I saw it on lore, but it wasn't in my mailbox for some hours. That time I looked a bi tinto it. I went into the gmail UI and searched for rfc822msgid:$id, nothing. It was neither there on IMAP or in the UI. However when the E-Mail finally arrived I looked at the raw headers, and all the "Received" headers (including GMail's own internal routing) were within a couple of minutes of Junio having sent the mail (and in the meantime it went through vger etc.). So, I'm hazy on E-Mail infrastructure details these days (but worked no it in a past life), but that really seems to me like GMail in fact got the E-Mail, but it was just sitting in some local queue of theirs before it got served to me. Right now I can't see the mail I'm replying to in my inbox[1], but I can report the full headers once it arrives if that helps. 1.
