Challenge:
- postfix/error[dddd]: ... status=deferred (delivery temporarily suspended: connect to mail.server.tld[/var/run/dspam.sock]: Connection refused)
- mails are not delivered

Fetchmail collects mails but dspam doesn´t accept a connection
And than i read in my /var/log/maillog:
May 17 11:12:49 home postfix/qmgr[31743]: 0C03E494538: from=, size=7362, nrcpt=1 (queue active)
May 17 11:12:49 home postfix/qmgr[31743]: 0C03E494538: to=, relay=none, delay=304891, status=deferred (delivery temporarily suspended: connect to /var/lib/dspam/dspam.sock[/var/lib/dspam/dspam.sock]: Connection refused)

/etc/postfix/master.cf:
lmtp unix - - - - - lmtp
CHANGE TO
lmtp unix - - n - - lmtp

Hint: chrooted vs. non-chrooted run of lmtp / dspam.
