OK,  so the clients are sending email to addresses that are not local to
your lan's server (otherwise there would be no relaying attempt)

Have you considered turning on authentication on the lan server,  you can
then allow relaying only from an authenticated "client".

Sending directly from the client to the recipient address's server  is
valid, doesn't need authentication, and relatively simple to do  using
smtplib.py .  However,  nowadays this may be problematic because of
increasing anti-spam measures that *might* cause the email to be refused on
a variety of criteria (IP address (RBL) ,  IP address reverse lookup,
possibly SPF, etc etc ).

import smtplib
try:
    s = smtplib.SMTP(outgoing-server)
    failed = s.sendmail(out_from, to_list , msg)
except smtplib.SMTPRecipientsRefused, x :
    do something  # for recip in x.recipients:  info = x.recipients[recip]
except smtplib.SMTPDataError, x:
    do something  # x[0], x[1]
except smtplib.SMTPSenderRefused, x :
    do something  # x.sender, x.smtp_code, x.smtp_error
except:
    do something

(failed contains a list of failed recipients if *some* but not all failed,
if all failed then use
except smtplib.SMTPRecipientsRefused, x :)

Alternatively there are some free mail SPs out there that provide
authenticated outgoing servers that  you could use if  you can't turn on
authentication on your lan server.
