Which in fact underneath probably runs /usr/lib/sendmail, so maybe the
package system is telling you it needs an MTA (SMTP server), because of this
dependance. A way round this, is to make a wrapper for local delivery
agent, with compatible calling to whatever the command line mailers are
using (/usr/lib/sendmail is traditional), and then use a local delivery
agent, which normally procmail under Linux, and /bin/mail on UNIX.
Easier still to install it and simply not run the daemon, as said previously
connecting to an SMTP server as a client, is not a significant security
