Installation of Procmail

This package does not come with a test suite.

Install Procmail by running the following commands as the root user: 

sed -i 's/getline/get_line/' src/*.[ch]                   &&
patch -Np1 -i ../procmail-3.22-consolidated_fixes-1.patch &&

make LOCKINGTEST=/tmp MANDIR=/usr/share/man install       &&
make install-suid

Command Explanations

sed -i 's/getline/get_line/' src/*.[ch]: This renames procmail's getline function to avoid conflict with the getline function from glibc.

make LOCKINGTEST=/tmp install: This prevents make from asking you where to test file-locking patterns.

make install-suid: Modifies permissions of the installed files.

Configuring Procmail

Config Files

/etc/procmailrc and ~/.procmailrc
