RE: spamproblem - hilfeee
just seems as if the credentials are cached somewhere still. Did you try restarting imap ?
Also it seems as if your /etc/postfix/ispcp/domains , sender-access not contain the actual data.
Can you pls take a look if info@noname.tld still exists in there ?

If you use courier for imap/pop3 they retrieve the login data from mysql - so please also check with PMA if they still exist there.

RE: spamproblem - hilfeee
ja, /etc/postfix/ispcp/domains , sender-access stimmt alles ... sämtliche mail dienste neugestartet und ssl zertifikate neu erstellt ...
ich habe ja diese mailadresse gelöscht und sonst ist sie nirgends vorhanden,
habe nun eine zusätzliche sender-check eingebunden und die mailadresse info@noname.tld auf reject gesetzt, das klappt zwar aber das eigentliche problem ist nicht gelöst:
Code:
Jul 24 14:15:49 sr01 postfix/smtpd[25870]: NOQUEUE: reject: RCPT from unknown[183.130.81.2]: 554 5.7.1 <info@noname.tld>: Sender address rejected: Access denied; from=<info@noname.tld> to=<546426300@qq.com> proto=ESMTP helo=<md>
Jul 24 14:15:49 sr01 postfix/smtpd[25870]: lost connection after RCPT from unknown[183.130.81.2]
Jul 24 14:15:49 sr01 postfix/smtpd[25870]: disconnect from unknown[183.130.81.2]
Jul 24 14:15:50 sr01 postfix/smtpd[28386]: connect from unknown[183.130.81.2]
