The qmail Handbook

qlogtools is a set of utilities used for producing and analyzing logs from services managed using daemontools, especially qmail. Particularly handy are:

• qlogselect, which extracts messages from a multilog qmail-send log file from a particular sender or time period

• tai64n2tai, which converts multilog timestamps to the format that qmailanalog requires (see "qmailanalog" in this appendix)

• multitail, which displays data appended to a named file, even if the file is cycled—like multilog's current

qlogtools was written by Bruce Guenter, who maintains a Web page for it (http://untroubled.org/qlogtools/).
