These diffs for pflogsumm versions 1.1.1 and 1.1.3 work around a
change in the Postfix 2.9 default master.cf file.

That change made the logging from submission and smtps services easier
to distinguish, by changing postfix/smtpd into postfix/submission/smtpd
and postfix/smtps/smtpd, respectively.

Below are diffs for pflogsumm-1.1.1 and pflogsumm-1.1.3 (beta).
Choose one that fits your pflogsumm version.
