Logcheck devel - Feb 2013 - Bug#699427: Change in Postfix 2.9.3 log messages : corrective

I forgot that the end of the line ": Name or service not known"
isn't printed anytime. A matching regexp for those messages would hence be:
^\w{3} [ :[:digit:]]{11} [._[:alnum:]-]+ postfix/smtpd\[[[:digit:]]+\]: warning:
hostname [^[:space:]]+ does not resolve to address ([[:xdigit:].:]{3,39})+(:
Name or service not known)?$
