From courier-0.47.20041129: if use mailwrapper ; then mv ${D}/usr/bin/sendmail ${D}/usr/bin/sendmail.courier rm ${D}/usr/bin/rmail insinto /etc/mail doins ${FILESDIR}/mailer.conf else Versions of courier PRIOR to that had made no accommodations for mailwrapper. Doing this (until i get something better) should build the new courier without the link in sbin, after which point, mailwrapper should be able to build: USE="mailwrapper" emerge --nodeps =mail-mta/courier-0.47.20041129
ok, both current versions of courier have been updated to cooperate better with mailwrapper, and they will try to install themselves before mailwrapper, removing their sbin link in the process if the mailwrapper USE flag is set. However it is OK if mailwrapper overwrites the file. So, set USE="mailwrapper", then: FEATURES="-collision-protect" emerge courier mailwrapper
