Recently we have had situartion where the staff could not send Emails to External Users.
I check the Error messages and found out that we were Blacklisted.
I removed it and all was good but the same thing happend and again it was blocked by CBL.
I tried to get in contact with CBL but they do not have any of there contacts listed.
Will any of you out there have any information on how to get in contact with CBL.
Things I have checked.
Scan Mail and IMSS are working fine and have not reported any spams.
All Emails going out are sent to my IMSS server which relays it to External Sites.
I have checked and done a Scan for Virus and Malware on my Network and everything came clean.
The Changes to my Network are:
1. I have put in a WEB Server but it is in its own DMZ
2. I have Installed Exchange2007 CAS and MB Server
3. I have enabled Outlook anywhere on my CAS Server
I am trying to get this sorted out so that my Domain does not get blacklisted again.
