Postfix logs this when pcre_exec() returns a match count of zero.
According to documentation:
If the vector is too small to hold all the captured substring offsets,
it is used as far as possible (up to two-thirds of its length), and the
function returns a value of zero.
About 10 years ago, someone decided that Postfix needs no more than
99 () in a PCRE regular expression. I suppose this is one of many
things in Postfix that should eventually be made configurable.
For now, you would have to edit dict_pcre.c, and update the
PCRE_MAX_CAPTURE constant.
