Hello,
exploring my log files in /var/log/ on different SME i have seen something interesting :
we can see two different extension to log files like qmail or qpsmtpd.
*.u and *.s
It seems that the most common used to be .s (as i used to have a script working with this extension for awstats and qmail) but on newer SME i only see .u files or most .u files with one .s in the middle.
Somebody can point me out the reason of these two extensions ?
