If I open my browser and access my DWA mail file and send an smtp email to recipient@domain.com, they receive the message fine.If I open my Notes client and send to the same recipient, I get the following NDR:
5.1.0 - Unknown address error 550-‘sorry, mail to that recipient is not accepted (#5.7.1)’ (delivery attempts: 0)
I had a couple other people in our department try it, same thing (dwa ok, client not).
Only happens for this one particular smtp recipient.
Is this bizarre or what?
any ideas?
TIA,

Is your DWA server the same as the server they are connecting through Notes?
Is there any antispam server in the middle?
I am guessing you have a restriction in your SMTP outbound control tab.

Same server hosing DWA and Notes. They access their mail file via the server, not a local replica.No server in the middle.
Nothing populated in the SMTP outbound control tab

What happens if you try to make a telnet to the port 25 and try to send a mail from there?
Is there a rule in the server that might be blocking them?

I did a view show page source and found the failure message is being generated by our iron port server
