i could be missing something but ...

the tail -f | perl command will not work until the perl script is done getting its data and the stream closes ... the cat | perl command results in a closed data stream so it does not have the same issue ...

unless your perl script is able to generate the formatted report and update the same report immediately as new data streams in, i think you would be better off running a check on the log file or periodically just tailing a portion of it and then run it through your perl script ...

NAME
matcherrc2perlfilter -- Conversion of matcherrc rules to perl DESCRIPTION
This script converts matcherrc filtering rules into perl_filter rules for usage with the claws-mail-perl-filter plugin of the Claws Mail mailer. USAGE
matcherrc2perlfilter No arguments required. Conversion is done for current user only. FILES
$HOME/.claws-mail/matcherrc Input file where standard filtering rules lie. $HOME/.claws-mail/perl_filter Output file written by this script. Converted rules are appended if the file already exists, so be careful when running the script more than once. BUGS
This conversion script doesn't produce nice Perl code and is just intended to get you started. If you choose to use the Perl plugin, consider rewriting your rules. SEE ALSO
