Hi, I think it's not an email issue but a routing one.
Zayo in Sydney shows: ? 67.231.157.0/24 B 170 120 4294967294 38195 19551 22843 I unverified >203.153.18.37 ? B 170 120 3491 19551 22843 I unverified >64.125.28.18 64.125.28.50 AussieBB in Hawthorn shows: Advertised IPv4 Unicast paths to peers (in unique update groups): 61.245.147.114 19551 26211 209 3356 1299 19551 22843 It's not wrong, but it's weird. AussieBB's router in LA has some decent routes to Proofpoint over Arelion and Cogent but doesn't advertise them to peers :( Best of luck, Mike
