To do such a thing, you need to install the `mbstring` PHP Extension, compile it with `PEAR` and enable the `mailparse` extension after the `mbstring` (using a higher digit). It should be necessary to alter source code to remove the check on `mbstring` existence due to an error in this check. ### Health Score 17 — LowBetter than 6% of packages Maintenance38 Infrequent updates — may be unmaintained Popularity6 Limited adoption so far Community9 Small or concentrated contributor base Maturity14 Early-stage or recently created project Bus Factor1 Top contributor holds 65% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
