SMTP Settings are currently being worked on (we got the fix a.t.m. but want to confirm/ fix 2 other small bugs before pushing out the update, it should be ready within the next couple of days).
Onn user ticket submit we have removed the email to the client (as he submitted it AND can see the submitted ticket directly online).
Only when admin replies the client gets a email.
So normal workflow:
1) Email created by customer --> Admins (depending on osTicket email settings in department/ groups) receive mail (from the default system email address defined in osTicket)
2) Admin replies --> Customer gets email (with the department email address + name set in osTicket)
3) Customer replies --> Admins (depending on department/ group setings) receive mail (from the default system email address defined in osTicket)

Marco
