Hallo Gemeinde,
> relayhost = [smtp.strato.de]:25
dank der vielen hilfreichen Ratschläge hier in der Newsgroup ich bin
zwei große Schritte weitergekommen.
1. Postfix spricht mit dem richtigen Server bei Strato; der Tipp von SW
war goldrichtig. Mit den eckigen Klammern um den Hostnamen wird der
Server smtp.strato.de direkt angesprochen.
2. Mein Mailversand klappt jetzt, es werden wieder Mails ausgeliefert.
Allerdings spricht Postfix auch nach Installation des Pakets
cyrus-sasl-md5 nur AUTH PLAIN, und nicht CRAM-MD5

Gibts es eine Möglichkeit Postfix zu zwingen CRAM-MD5 zu verwenden, oder
ist AUTH PLAIN das Maximum was die beiden Partner an Verschlüsselung
aushandeln können ?
ciao, Stefan
