Thanks for your explaination about exim's behaviour. However, now that
I've had more time to investigate, I don't think the problem is their
callouts. I suspect verizon has just plainly broken something with
their incoming mail servers / network:

$ telnet 206.46.170.12 25
Trying 206.46.170.12...

tcptraceroute appears to confirm that something's up:

15 p1-0.verizonol4.bbnplanet.net (4.24.242.94) 134.413 ms 136.832 ms 136.632 ms
16 gigchannel9-0--12-0.core1.dfw-tx.vzlink.com (206.46.128.78) 137.487 ms 137.318 ms 136.858 ms
17 * * *
18 * * *

It appears to be the same story from a couple of other networks in the
UK.
