Lotus Domino 7 Inbound mail server

I have been getting a lot of spammers using my
Domino 7 mail server.

I am unable to tell what user they are logging in as.

I have a fear that they are login  with out a password.

How can I check to be sure the server is only allowing
Authenticated users to use the system.

If your server is a so-called open relay, they don't even have to log in. You can test it using http://mxtoolbox.com/diagnostic.aspx

You probably have to close the open relay, by reconfiguring the Domino server (which should have been done years ago, really...). Read this page from the Admin Help database or search that database for "Preventing unauthorized SMTP hosts from using Domino as a relay".

PS And may I suggest you upgrade your server, Domino R9.0.1 is available already!

Well seems I was wrong
I ran your test

      SMTP Open Relay      OK - Not an open relay.

and I am not an open relay

But I guess it is a poor username password combo.

I captured some network traffice hope I can find it.

Any other suggestions.

How do you know they use your server? Can you show us some extracts from your server's log.nsf database, especially from the Miscellaneous and Mail sections?

If they use POP3 or IMAP, you can see them in domlog.nsf, if you activated http logging in that database.

I opened a new question after looking at the firewall dumps

Sorry, but you cannot close a question like that, and with a "C". Why didn't you supply us the information I asked for? It'll help you (ans us) to investigate the problem a lot further.

I'm going to ask for this question to be reopened.
