Switch off SMTP

[Jochen May]

Hi!

I get quite often error messages like this in my postfix.log:
Oct 30 10:15:15 kolab <info> postfix/smtp[8841]: C33CD66AB8: host mx00.1and1.com[74.208.5.3] refused to talk to me: 554 RBL
rejection: http://www.spamhaus.org/query/bl?ip=62.227.247.14

Is there a way to avoid this? I only use smtp for sent local mails.

Btw, somebody a idea what this mean to mean:
Oct 28 17:39:12 kolab <warning> postfix/smtpd[8307]: warning: database /kolab/etc/postfix/canonical.db is older than source file
/kolab/etc/postfix/canonical

Thanks + Greetings
