Where can I do any changes to modify the Spam-Tag in Mail-Subjects from "[!! SPAM]" to "###SPAM###". Its not an option to change all rules in Outlook on any computer in our company.

hi there,

well, this tag is hardcoded in the application and cannot be changed.
however, you can consider following:
--- switch off marking the Subject field in the application; the application will only insert X-SpamTest-* fields;
--- in the mailing system that stands after mailgw or in the mailing system that performs final delivery to the users' mailboxes, add a rule that will change the Subject field on the desired manner depending on the contents of the X-SpamTest-Status (or X-SpamTest-Status-Extended) field.

For example, add a rule 'if X-SpamTest-Status = spam then prepend ###SPAM### to the Subject field' or something like this.

Such the rules changing the Subject field can be implemented very easy with postfix, sendmail and some other mailing systems, as well as within maildrop\procmail (I'm not sure about MS Exchange though...).

The possible values for the X-SpamTest-Status* fields can be found in the manual on the mailgw application.
