[mailop] Any evidence of SMTP smuggling in the wild - yet?

Has anyone detected or seen any evidence of SMTP smuggling in the wild? I’m trying to get an independent read on how quickly the bad actors have (or haven’t) picked up on this, yet. Cheers, Tom ___ mailop mailing list mailop@mailop.org https://list.ma

[mailop] Anyone tried and couldn't use SPF macros due to interoperability issues?

Has anyone recently encountered any “modern” mail system that can’t handle SPF macros? The RFC is about a decade old at this point. I don’t care if Exchange 2003 can’t handle them, but does anyone know any reasonably modern system that doesn’t? I know all our systems like them just fine, and I’

[mailop] How to get Google to set a null MX for gmail.co ?

[mailop] Interesting fallout from the FaceBook outage?

ServiceNow (NOW) saw what seems to be an interesting side-effect of the Facebook DNS/routing issue from earlier this week. Looking for anyone else who saw the same thing, or to see if I’m mis-interpreting the evidence. We started seeing a large number of “421 local policy violation” errors for

Re: [mailop] Complete set of rules for delivering to t-online.de ?

Perfect, that's what I was looking for. Our customers still need more education (and tooling) around bounce handling. We're working on it. Since they control their own databases, which we are not permitted to see, we have to work with them to help them improve their email hygiene. They also c

Would someone from t-online.de please publish the COMPLETE and DEFINITEIVE set of ALL rules for sending to your customers? Preferably on your web site instead of in mailops, so that everyone can see them? I’ve seen bits and pieces here, with many unanswered questions. It’s not at all clear what

[mailop] Anyone using clustered DoveCot?

I’d be interested in chatting with anyone who has rolled out (or failed to rollout!) Dovecot in a cluster. Especially if you’re using an object store. Tom ___ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
