Comment notification emails

...there's a suggestion that it's somehow related to chiark. Experimentally I've bypassed SAUCE entirely, and this doesn't seem to have helped; there is still no evidence of LJ attempting to connect at all, never mind connecting and then being turned away. Which makes me suspect the problem lies outside chiark.

(update: it does seem to be SAUCE after all.)

I have no idea what e-mail address you've given livejournal. Is it in a domain that has completely vanilla DNS? Is there anything funny about the other MXes? Are the other MXes seeing anything from Livejournal?

This is a handy tool for exhaustively determining all possible answers someone might get to a DNS query, by the way.

My comment notification emails go to an address at ysolde.ucam.org , which is handled by chiark, and seem to arrive fine, so....

[ewx.livejournal.com]

Ah, good. I think that rules that out, then.

[ewx.livejournal.com]

In fact, it is SAUCE's fault after all.

Well that's easy enough to test, if I switch to my work address for today. All I have to do now is generate some comments to me :-)

[lnr-at-work.livejournal.com]

And oh look, here's a spare person who can comment :-)

[lnr-at-work.livejournal.com]

And that comment just arrived immediately in my work inbox.

How naughty of it. What made you change your mind?

[ewx.livejournal.com]

Switch to a non-SAUCE'd address initially had no effect, but comments since then do seem to have turned up. (Perhaps there was some coincidental transient delay somewhere.) After that I spent more time studying logs and eventually found a smoking gun.

[lnr-at-work.livejournal.com]

All my addresses are set to lax, is this not adequate?

[lnr-at-work.livejournal.com]

Hmm, and grepping the logs for eleanorb I can't see any addresses being rejected that seem to have come from LJ.

[ewx.livejournal.com]

No, the firewall accepts or rejects packets before SAUCE gets to think about them.

[lnr-at-work.livejournal.com]

Gah! And this doesn't happen with completely unSAUCEd addresses? How do I produce one of those then? ISTR I have a greenend.org.uk one, but it would be nice if I could do that with chiark addresses.

And any idea why it's just started being a problem since around 9am on the 12th?

[ewx.livejournal.com]

It's a SAUCE bug and seems to be in hand. I expect there'll be an announcement.

[ewx.livejournal.com]

Ah yes. See /info/new.

Thanks love!
