Hallo Zusammen,

ich versuche seit Stunden einen Weg zu finden, das PMG Notification-Mail an Sender über Postfix versendet:

Aber ich bekomme ich die Meldung:

Mar 23 15:12:22 MailG postfix/smtp[5259]: 446268110D: to=<xxxtest123xxx@online.de>, relay=mx01.emig.kundenserver.de[217.72.192.66]:25, delay=594, delays=594/0.11/0.12/0, dsn=4.0.0, status=deferred (host mx01.emig.kundenserver.de[217.72.192.66] refused to talk to me: 554-kundenserver.de (mxeue111) Nemesis ESMTP Service not available 554-No SMTP service 554-IP address is block listed. 554 For explanation visit https://postmaster.1und1.de/de/case?c=bl&i=ip&v=109.250.xxx.xxx)

Ok die Reverse-Lookup fehlt, aber ich habe einen Dyn-DSL ohne feste IP und nu? Kann ich Postfix so umbiegen, dass er einen SMTP-Relay benutzt?

Was mache ich falsch oder habe ich vergessen? Danke
