logrotate rotating too much

[Sven Burgener <svenb@bluewin.ch>]

Hi all

My logrotate contains a section for exim's main log file:

/var/log/exim/mainlog {
    missingok
    monthly
    create 0664 mail mail
    rotate 1
}

Why though does it compress exim's other log files, too?!

# ls -l /var/log/exim/
total 220
-rw-rw-r--    1 mail     mail        87254 Jul  8 12:17 mainlog

Also, what are good values for setting up logrotate? I am not much
familiar with the tool yet. :)

Any help appreciated...
TIA
