Hi,

is there a way to make syslog-ng rewrite a log message before it is written to disk, e.g. to remove all sender and recipient fields the mail server did log?

Are you sure that you want/need to do all of that rewriting work within syslog-ng? There are tons of tools you can run *after the fact* to strip out characters or fields in a text/log file. That being said, you can probably use "syslog-ng-anon", a 3rd party patch to syslog-ng, that will strip out IP addresses (or anything else using regular expressions). The patch has been mentioned, at least once before, on this mailing list. -Matt Cuttler
