Official Mirror:
The Linux Standard Base ( is a standard core system that third-party applications written for Linux can depend upon. This package contains nothing else than a fake /usr/sbin/sendmail command to fulfill the LSB's requirement of providing this command without requiring an MTA to get installed, which once introduces a daemon which can cause security problems and second, users get asked questions about how they want their MTA configured when in reality they simply wanted to install a desktop application or a printer driver, but the dependency on LSB compliance pulls in an MTA with the installation. The LSB requirement on /usr/sbin/sendmail comes from old times where Linux and Unix machines had all fixed IPs and did server tasks in data centers. Today's typical desktop Linux machines do not do local e-mail any more as users use external e-mail services. The /usr/sbin/sendmail always exits with exit status -1 (255) and sends a warning message to stderr, so that if a program actually tries to send e-mail via the sendmail command the user gets note.
