Telnet to port 25 from systems not on 128.135.12.0/24 proceeds as expected.

A typical Courier log excerpt looks like this:

Jul 22 12:17:41 [courieresmtpd] started,ip=[128.135.12.12] Jul 22 12:17:41 [courieresmtpd] error,relay=128.135.12.12,msg="502 ESMTP command
error",cmd: XXXX midway.uchicago.edu Jul 22 12:19:05 [courieresmtpd] [128.135.12.6]: Connection timed out

...and that's where I'm stuck for now. If anybody knows what I'm missing, please drop me a hint.
