"we do not relay" problems

[Chris Jensen]

i've got a client that gets a lot of "we do not relay" problems, 
despite setting up their outlook to log in to send messages and recieve 
messages before they send.  i can't isolate their network because they 
are mobile.  what else can i do to make sure they are able to send 
their mail?

some log entries:
##############
12:11:42 4 SMTP-490([24.12.176.132]) Looking for vette.XXXXX.com
12:11:42 1 SMTP-490([24.12.176.132]) SPAM? Recipient 
'<[EMAIL PROTECTED]>' rejected: relaying to [130.36.44.76] is 
not allowed
12:11:42 4 SMTP-490([24.12.176.132]) Sending 571 
<[EMAIL PROTECTED]> we do not relay.\r\n

##############
the SMTP settins are set to treat authenticated IPs as Client ones, 
Relay for Clients Only.  what else can i do?

thanks in advance!
