When a mail server receives mail via SMTP, the standard requires
that it adds a header with:
Received: ....stuff.....
Many MTAs count the number of such message header lines and report
a "Maximum hop count exceeded" error because the number exceeds
some upper bound.
With Postfix, the default is "hopcount_limit = 50".
Your "telnet" message had no such header, while the "non telnet"
message presumably had several. That's why one triggers the
error and the other does not.
