Well seems I was wrong <br />
I ran your test <br />
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;SMTP Open Relay &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;OK - Not an open relay.<br />
<br />
and I am not an open relay<br />
<br />
But I guess it is a poor username password combo. <br />
<br />
I captured some network traffice hope I can find it. <br />
<br />
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? <br />
<br />
If they use POP3 or IMAP, you can see them in domlog.nsf, if you activated http logging in that database.

Sorry, but you cannot close a question like that, and with a &quot;C&quot;. Why didn't you supply us the information I asked for? It'll help you (ans us) to investigate the problem a lot further.<br />
<br />
I'm going to ask for this question to be reopened.

Lotus Domino 7  Inbound mail server

Lotus Software produced the Lotus 1-2-3 spreadsheet program, and later developed Lotus Notes, a groupware and email system. Following its acquisition by IBM, the Notes and Domino client/server collaborative platform were expanded to include functions such as email, calendars, to-do lists, contacts management, teamrooms, discussion forums, file sharing, microblogging, instant messaging, blogs, and user directories. IBM also release SmartSuite, a comprehensive office suite, and followed that with Symphony, unrelated to the Lotus suite of the same name.

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
