Danke für die Antwort.
Ich habe mich mal auf der Seite umgeschaut und auch den besagten Parameter mal auf eine stunde gesetzt (und auf 0). Jedoch auch hier ohne erfolg.
Könnte es vielleicht daran liegen das der Server die Mail nicht selber ausliefert, sondern die Mails wieder an den SMTP vom Provider übergibt?
