While packaging OpenDMARC 1.4.1.1 for Debian we discovered that the function
check_domainin libopendmarc/opendmarc_policy.c was added to the public ABI:https://salsa.debian.org/kitterman/opendmarc/-/blob/1ec111cf4785bcbd786d2f1bb443ec0c5810a0d0/debian/libopendmarc2.symbols#L3
This looks like a mistake. The function is not in any header files, doesn’t conform to naming conventions for libopendmarc, isn’t documented, and is used only locally in libopendmarc/opendmarc_policy.c.
The proposed change makes the function
static.
