Hi I'm trying add new rules to logcheck, but as soon as it get dynamic my new rules fails. For instance whenever postfix checks user/password in my mysql-table, it's written i the log and i get a mail. Here i tried to add new rules, but only the static works. # Extras - Mysql Connection ^\w{3} [ :0-9]{11} [._[:alnum:]-]+ postfix/smtpd\[[0-9]+\]: sql auxprop plugin using mysql engine ^\w{3} [ :0-9]{11} [._[:alnum:]-]+ postfix/smtpd\[[0-9]+\]: sql plugin try and connect to a host ^\w{3} [ :0-9]{11} [._[:alnum:]-]+ postfix/smtpd\[[0-9]+\]: sql plugin trying to open db '[A-Za-z0-9_-]' on host '[0-9].[0-9].[0-9].[0-9]' ^\w{3} [ :0-9]{11} [._[:alnum:]-]+ postfix/smtpd\[[0-9]+\]: begin transaction ^\w{3} [ :0-9]{11} [._[:alnum:]-]+ postfix/smtpd\[[0-9]+\]: sql plugin create statement from userPassword [A-Za-z0-9_-] smtp.mailfx.dk ^\w{3} [ :0-9]{11} [._[:alnum:]-]+ postfix/smtpd\[[0-9]+\]: sql plugin doing query select [A-Za-z0-9_-] from [A-Za-z_-] where username='[A-Za-z0-9_-]'; ^\w{3} [ :0-9]{11} [._[:alnum:]-]+ postfix/smtpd\[[0-9]+\]: sql plugin create statement from cmusaslsecretCRAM-MD5 [A-Za-z0-9_-] smtp.mailfx.dk ^\w{3} [ :0-9]{11} [._[:alnum:]-]+ postfix/smtpd\[[0-9]+\]: commit transaction And in syslog it's mentioned every DDNS added to the zone-files and i get a mail.

And what if i want to add a new service to the "logcheck/ignore.d.server" directory. Do i just add a new txt-file and it will be included at once? So if anyone can help me with creating new rules, i would me very happy... Thanks in advance... /Lars
