I setup email send by smtp on 587 port: mail was send successfully, but in the log I've:Impossibile inviare mail via SMTP: smtp.100asa.it Failed to set sender: XXX@[deleted]00asa.it
Take a look here:http://forum.osticket.com/d/discussion//resolved-1-9-1-email-smtp-problemIs that correct set up in your environment or not?
