I forgot to mention, the service call was logged on the 11th November 2002, thread no. 26332, and the one asking if it had been dealt with in a satisfactory manner on the 19th. Not a peep out of them since.

The solution in that article was not very encouraging. John Tolmachoff MCSE, CSSA IT Manager, Network Engineer RelianceSoft, Inc.

Yes, GFI's uninstalls leave a great deal to be desired, i have had many problems with there software, indeed there is still a service call open for me regarding download security not installing correctly (tells me that the virus definition subscription has expired, right from day one.), of which I have heard nothing, ( apart from a mail from them asking if the call had been dealt with ok, to which I replied in the negative,), and also with mail security, which was resolved by a vb script supplied by GFI. I always test GFI products thoroughly, before installing on production servers for customer,s. Just as well. Steve From:John Tolmachoff Sent:Fri 07/03/2003 08:15 PM To:[ISAserver.org Discussion List] Subject:[isalist] GFI http://www.ISAserver.org Interesting read: In some scenarios, the sink bindings may exist in the Exchange 2000 Server metabase but the sink is not properly registered in the registry. When this occurs, the SMTP protocol does not create the sink when it tries to process the "MAIL FROM" command. As a result Exchange 2000 Server drops the connection, and the outgoing mail is not processed. This issue may occur when a third party program, for example GFI Mail Essentials, is installed and then incorrectly or incompletely removed. GFI Mail Essentials contains an add-on named Mail Security. Mail Security installs an outbound SMTP sink that verifies the validity of the sender address. If improperly removed, the sink may remain although the sink is no longer correctly registered. When the "MAIL FROM" command is initiated by Exchange 2000 Server, the sink fails and Exchange 2000 Server drops the connection.
