Perhaps you'll find "collate" useful:
https://github.com/vdukhovni/postfix/tree/master/postfix/auxiliary/collate
It does often require minor adjustment to its regular expressions for
matching the initial portion of your log messages, whose format is
system-dependent:
https://github.com/vdukhovni/postfix/blob/master/postfix/auxiliary/collate/collate.pl#L9-L12
to search for a multi-line block (delimited by blank lines) match a
particular pattern, I use:
$ perl -ne '
BEGIN {$/="\n\n"}
print if m{some-perlre-pattern}
' [input files... (or else stdin) ]
