in the new ones there is nothing and I asked my boss if he ever did some change or smt and he told me no.
"4.- Right now we are in the 4th try but know I am alone (no staff and no users ) with the config and not much more, the plan is for the system to send every mail only to me, so its not bothering clients and staff, and when it finishes, then I add back the clients and staff."
this kinda worked cause it didnt send any mail but now we are going to try the same plan but with the official db.
thanks for all the help btw
