Sorry, I've lost track of where exactly in the thread we are now, but this is a good one to reply to. From here in the UK: $ host googlemail.com googlemail.com has address 216.58.204.69 googlemail.com has IPv6 address 2a00:1450:4009:80c::2005 googlemail.com mail is handled by 30 alt3.gmail-smtp-in.l.google.com. googlemail.com mail is handled by 40 alt4.gmail-smtp-in.l.google.com. googlemail.com mail is handled by 5 gmail-smtp-in.l.google.com. googlemail.com mail is handled by 10 alt1.gmail-smtp-in.l.google.com. googlemail.com mail is handled by 20 alt2.gmail-smtp-in.l.google.com. so we start off with a different address for googlemail. :) $ host gmail.com gmail.com has address 216.58.198.165 gmail.com has IPv6 address 2a00:1450:4009:80c::2005 gmail.com mail is handled by 20 alt2.gmail-smtp-in.l.google.com. gmail.com mail is handled by 30 alt3.gmail-smtp-in.l.google.com. gmail.com mail is handled by 40 alt4.gmail-smtp-in.l.google.com. gmail.com mail is handled by 5 gmail-smtp-in.l.google.com. gmail.com mail is handled by 10 alt1.gmail-smtp-in.l.google.com. gmail has the same different address $ telnet gmail-smtp-in.l.google.com 25 Trying 173.194.76.27...

And I get to telnet to a different host as well, but it seems to behave like Per's one, not like the North American one(s). Or maybe it knows that Per and my domains are run by fine upstanding people who don't send spam? :) So trusts us to send plaintext. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
