Yes. It turned out to be trying to query my non-existant ident server, and
then ignoring the ICMP message my firewall rules sent it. It just sat there
in a staring match with my mail server until my end timed out. An unrelated
but confusing effect is that the other end only accepts one connection from each
source IP address, so when I telnetted to the other end it dropped the first
connection.
Fix: install a no-op ident server.
