hi, recently we changed the server ip address as the smtp server address too, after several tests, listserv can't send emails even if the log file says it does. With another software (GroupMail). Is there a way to know if Listserv is deliveryng the emails to the smtp? here is the change in site.cfg SMTP_FORWARD=148.244.85.213 Where else do we have to do some changes in the configuration that may be we forgot? best regards,
