I've gotten a number of replies on my sendmail posting. Thanks to all
who responded. From what I've gathered it appears that the problem is
not with sendmail itself, but is a manifestation of a problem on
part of the Internet. There is a gateway which is clobering packets
greater than about 1k. This would cause sendmail to hang when
attempting to deliver messages > 1k because the packets with the message
couldn't get through. I'm not sure which hosts this affects, but the
problem is being worked on.
On a related note phil@ux1.cso.uiuc.edu mentions:

There is a problem in sendmail v5.61 that causes it to hang on
large headers (such as a large To: field). The problem and a fix were
posted on comp.bugs.4bsd. If anyone is interested in it let me know.
