Hallo.
ich finde gerade die Lösung nicht im startpage.com.
Es gibt 3 Server von einem Kunden die es einfach nicht schaffen mit meinem Server eine SSL Verbindung aufzubauen. Ich habe bereits wieder SSLv3 aktiviert und trotzdem bekomme ich immer diesen Fehler.
postfix/smtpd[27053]: SSL_accept error from <SERVER>: -1
Nun wollte ich diese Maschinen explizit aus dem SSL rausnehmen so ala "smtpd_tls_security_level = none" oder STARTTLS ganz deaktivieren für diese Server.
Geht das im
postconf mail_version mail_version = 2.11.0
LG Aleks
