Re: MIDRANGE-L Digest V4 #522

Lotus has a solution for this on their support website (support.lotus.com).  It
is described in document #179577 titled "MAPS Relay Spam Stopper Adds Lotus
Domin 4.6x Servers to Its BlackList".

Our Notes Administratior tells me that we implemented this fix and have tested
it successfully.

My apologies for posting a Domino problem on the midrange list, but I =
felt someone must of had a similar problem...

Our Domino mail server is being over-run with bogus email addresses =
(over 400 in less than 1 hour), apparently by a spammer attempting to =
use it to relay email. We searched the Domino site which had the =
following solution...

 Solution:

To do this, set the following parameters on the Server Configuration =
document:

  1. Open the Server Configuration document for the server on which you =
want to restrict relaying.
  2. Select the Router/SMTP tab, and the Restrictions and Controls tab.
  3. Then select the SMTP Inbound Controls tab, and under the Inbound =
Relay Controls section, set the following values:

      Allow messages from external internet domains to be sent only to =
the following internet domains: <blank>

      Deny messages from external internet domains to be sent to the =
following internet domains: *

      Allow messages only from the following external internet hosts to =
be sent to external internet domains: <blank>

      Deny messages from the following external internet hosts to be =
sent to external internet domains: *
  4. Stop and restart the SMTP task.
However, when we made this setting,  the administrator account was the =
only account able to send out email, so temporarily we have had to =
remove the recommended fix, and are continuing to be bombarded with =
spam. Has anyone experienced this and found a remedy? Any help would be =
appreciated.
