You're right. I compiled the new kernel with IPV6 enabled. I didn't have IPV6 in my previous kernel...

Re: Interesting new messages in logs
You're right that the answer to my question was IPV6 (I didn't have it compiled into the previous kernel). You're wrong that a port need not be open to receive connections. You will note in the log excerpt below that these are connection *attempts*, not actual connections.

Re: Interesting new messages in logs
To answer your first question, a port need not be open in order to receive connections. To answer your second, these appear to be IPv4 addresses encapsulated as IPv6 addresses. > Dec 19 12:21:04 cae88-102-101 /boot/kernel/kernel: Connection attempt to TCP > ::0001:25 from ::0001:1286 > Dec 19 12:24:08 cae88-102-101 /boot/kernel/kernel: Connection attempt to TCP > ::0001:25 from ::0001:1299 > Dec 19 12:27:13 cae88-102-101 /boot/kernel/kernel: Connection attempt to TCP > ::0001:25 from ::0001:1308 > Dec 19 12:39:28 cae88-102-101 /boot/kernel/kernel: Connection attempt to TCP > ::0001:25 from ::0001:1336 > Obviously, this machine is using log_in_vain, and it appears obvious > that these are local smtp transactions.

Check your configuration if you are listening on port 25 for IPv6 or not...
