I’ve just tired to install Postfix 3.3.1 on macOS X 10.13.6 High Sierra. Sudo make install finishes with:
Updating /usr/sbin/sendmail... mv: rename /Users/jlbrown/Downloads/postfix-3.3.1/junk to /usr/sbin/sendmail: Operation not permitted make: *** [install] Error 1 My make command was: make -f Makefile.init makefiles CCARGS='-DUSE_TLS -DUSE_SASL_AUTH \ -DDEF_SERVER_SASL_TYPE=\"dovecot\" \ -DDEF_COMMAND_DIR=\"/usr/local/sbin\" \ -DDEF_CONFIG_DIR=\"/usr/local/etc/postfix\" \ -DDEF_DAEMON_DIR=\"/usr/local/libexec/postfix\" \ -DHAS_PCRE -I/usr/local/opt//include \ -DHAS_SSL -I/usr/local/opt/openssl@1.1 \ -DHAS_MYSQL -I/usr/local/opt/mysql@5.7/include/mysql' AUXLIBS='-L/usr/local/lib -lpcre -lssl -lcrypto -L/usr/local/opt/mysql@5.7/lib \ Is this a SIP thing? Anyone come across this? How to fix? (I’ve been using Homebrew to install the other bits, but there is no formula for Postfix) Thanks, James.
