Which means that the Java side did not issue any SMTP commands after
connecting and issuing an EHLO or HELO.  Which perhaps indicates that
the sendmail side didn't respond with the expected
'250-smtp.example.com Hello ...' and following list of capabilities in
response.

What do you see if you telnet to localhost port 25 and then type in an
EHLO command? It should look something like this, although you
probably won't have the AUTH or STARTTLS parts unless you've modified
your sendmail:

    % telnet localhost 25
    Trying 127.0.0.1...
    Connected to localhost.
    Escape character is '^]'.

Nb. That sequence generates precisely the sort of log message you saw:

Hmmm... in server.xml I have:

            <Resource name=3D"mail/Session" auth=3D"Container"
                      type=3D"javax.mail.Session"/>

            <ResourceParams name=3D"mail/Session">
              <parameter>
                <name>mail.smtp.host</name>
                <value>smtp.infracaninophile.co.uk</value>
              </parameter>

              <parameter>
                <name>mail.smtp.port</name>
                <value>587</value>
              </parameter>
            </ResourceParams>

and in the per-application web.xml there is:

    <resource-ref>
        <res-ref-name>mail/Session</res-ref-name>
        <res-type>javax.mail.Session</res-type>
        <res-auth>Container</res-auth>
    </resource-ref>

and that seems to work very well.  This is from within a jail, and
speaking to sendmail in the host environment, which is why it can't
use a connection via localhost.  Port 587 is 'submission' -- the port
designated for local submission on new messages by the MUA,
distinguishing it from port 25 intended now for MTA to MTA transfer of
messages.  However, that's a new standard that has not yet reached
universal acceptance, so speaking on port 25 should work as well.

	Cheers,

	Matthew
