I keep getting the following error in my maillog: warning: trouble injecting bounce message, will try later I have tried to look this error up but I am not finding anything particularly helpful. I am currently running qmail-scanner and clamav however this error shows up even with qmail-scanner removed. P.S. If anyone is interested...I was receiveing an error from spam assassin when I had the SPF feature enabled that said it couldn't find some files... (some .pm files) that were in it's Perl includes. I discovered that although the SPF feature was installed, no checking was done by plesk to see if the required perl modules were installed. I had to use cpan and install Mail::SPF::Query module. Once I finally got these modules installed SpamAssassin stopped generating the errors. Apparently, so I am assuming, the SPF feature in Plesk 8 NOW functions where it was obiously failing.
