smfi_setconn description

The smfi_setconn API sets the socket through which the filter communicates with sendmail. The smfi_setconn API must be called once before smfi_main.

oconn

The address of the desired communication socket. The address should be a NULL-terminated string in proto:address format as follows:

smfi_setconn does not fail on an address that is not valid. A failure is detected only in smfi_main.

Notes:

If possible, filters should not run as root when communicating over UNIX/local domain sockets.
UNIX/local sockets should have their permissions set to 0600 (read/write permission only for the socket's owner).
