Comparing the output of ethereal and your telnet log, I can see two things:

1: the host you're reaching is different in each case. You reached
k2smtpout04-01.prod.mesa1.secureserver.net via telnet, and
k2smtpout02-01.prod.mesa1.secureserver.net via Courier. It's possible
that one of those hosts is not configured the same as the other. If so,
you'll have to contact the admins of that system to diagnose the problem
further. If I understand you properly, secureserver.net is providing
you with SMTP service, right? I'm not sure why they'd even look at the
recipient's domain.

2: your dump file is garbage. Those packets are definitely truncated
and possibly out of order. You should capture the stream with
ethereal/wireshark if possible. If not, try:
tcpdump -s0 -w/tmp/smtp.dump host k2smtpout.secureserver.net and port 25
