 Hello,

Since couple of days, it looks like my postfix server goes mad,
maybe because of some ugly spam i receive, but then after such
mail is received, my postfix logs lots of warnings every second:

Dec 2 10:52:23 postfix postfix/smtpd[9400]: 7562C3490: client=slycl907.st1.spray.net[212.78.214.147]

Here are some pflogsumm stats for today since 6 am:

mail_version is 2.0.16-20030917, patched with CDB support , compiled from source
OS= Linux 2.6.13.4 / Debian , x86

This is a small server at home, postfix configuration and version (mail_version = 2.0.16-20030917
patched with CDB support, yes i know it's old) haven't changed for about almost two years.

Time for me to upgrade ? :)

Thanks,

Philippe
