Some MTA's do hard limits. Some MTA's blow, as reflected in our own
Imail's 'hack attempts' radio button:
"Auto-deny possible hack attempts
If more than 512 characters are sent in an SMTP command other than
the SMTP DATA command, the remote IP address is temporarily put in
the "deny access" (Control Access) file until you stop and restart
the service and then disconnects. Sending more than 512 characters in
a command other than the SMTP DATA command would look like an attempt
to "hack" in to your server. You will not see the address in the
"deny access" list, but it is reported in the log file."
And I think there's something in one, or more, of the RFC's about max
length of header fields.
