When I installed SquirrelMail to a customer domain there where 25883 lines added to /var/webmin/miniserv.error !!!!
I did not know if something was wrong in the install script so I uninstalled it again, becauce I don't want the miniserv.error log get filled up whith these lines.
I can mail you the miniserv.error log if you like. (I don't think I should try to paste 25883 lines here.)
