Hi,

Lotus Notes is not my friend... I thought I knew how to do this. I am trying to block a sender from sending email messages to anyone in my organization. We have a pretty simple setup, one Notes Server (5.0.5), one domain....

What I have done is from the admin clinet, selected Configuration > Server > Configuration. Selected my server, selected the Router/SMTP tab. Selected Restrictions and Controls then selected SMTP Inbound Controls. On this page I added the email address to the "Inbound sender controls" > "Deny messages from the following Internet addresses/domains". I ran the admin requests and stopped/started the Note service. Still getting the emails from this address.

Any suggestions how I can stop these from coming through??

Thank you.
Dawn

Dawn,

Are you entering an IP address? or an email address?

You should enter the IP [125.60.10.0] in brackets and enable DNS in the configuration document to deny mail from a specific IP. Or the Host Name, if you know it.

Here's the excerpt from Notes Admin:
Restricting inbound SMTP connections  

Some users and organizations may attempt to send bulk unwanted email to your site. To prevent your mail system from accepting unwanted mail and prevent your servers from redistributing it, restrict who can connect to your mail system.
  1.     Make sure you already have a Configuration Settings document for the server(s) to be configured.
  2.     From the Domino Administrator, click the Configuration tab and expand the Messaging section.
  3.     Click Configurations.
  4.     Select the Configuration Settings document for the mail server or servers you want to restrict mail on and click Edit Configuration.
  5.     Click the Router/SMTP - Restrictions and Controls - SMTP Inbound Controls tab.
  6.     Complete these fields in the Inbound Connection Controls section, and then save the document:     Field     Enter
     Verify connecting host name in DNS     Choose one:
          Enabled to verify the connecting host name in the DNS
          Disabled (default) not to verify the connecting host name in DNS
          When enabled, this feature looks up the IP address of the connecting host in the DNS. If the IP address does not correspond to a valid host name, Domino accepts the connection but does not allow the host to transfer mail. Domino returns an error to the connecting host during the MAIL FROM command of the SMTP protocol and does not accept any inbound mail.
     Allow connections only from the following SMTP Internet host names/IP addresses     The host names and/or IP addresses that are allowed to connect to this server. If you enter host names and/or IP addresses in this field, only those servers matching these entries can connect to your server over SMTP; connection requests from all other servers are denied. For example, you enter
          lotus.com, ibm.com
          in the field. Domino accepts only connections from servers with host names ending in lotus.com or ibm.com. Domino rejects all other connection requests.
          Note  Enter IP addresses in brackets -- for example, [192.168.10.17]
     Deny connections from the following SMTP Internet host names/IP addresses     The host names and/or IP addresses that are not allowed to connect to this server. If you enter host names and/or IP addresses in this field, all servers except those matching entries in this field can connect to your server over SMTP; connection requests are denied only for servers matching the entries in this field. For example, you enter
          lotus.com
          in the field. Domino accepts connections from all servers except those with host names ending in lotus.com. Domino denies connections from servers with host names ending in lotus.com.
          Note  Enter IP addresses in brackets -- for example, [192.168.10.17]

Note  If you specify the same entry in an Allow field and a Deny field so there is a conflict between the two fields, Domino denies messages for that entry. The Deny setting takes precedence for security reasons. Be careful not to have the same entry in an Allow field and a Deny field for the same setting.

Hope this helps..

Thanks Marilyn..

I apologize for the delay in responding. The brackets were what I was missing... I should learn to read a little more carefully :)
