It appears that after upgrading our Smartermail from ver. 4 to ver. 12, all of our script based email stopped working. The new log viewing engine for ver. 12 is really inferior to just being able to see the logs because it leaves you "not believing" your search algorithm. In fact, if you do a search leaving the search string blank it still shows you nothing....exactly how to search for "EVERYTHING" and show the whole log?
Anyway, we are not finding any errors anywhere. Nothing shows up in the spool and if we search the error log for the sending email address or the final email we are not seeing anything.
