I attempted to uninstall the Postfix that was shipped with SUSE Linux,
and I got the following
errors after running

rpm -e postfix-2.1.1-1.4

error: Failed dependencies:
smtp_daemon is needed by (installed) fetchmail-6.2.5-49.3
smtp_daemon is needed by (installed) mailx-10.6-65.1
smtp_daemon is needed by (installed) mutt-1.5.6i-64.3
smtp_daemon is needed by (installed) cron-3.0.1-920.1
smtp_daemon is needed by (installed) mailman-2.1.4-83.4
/usr/sbin/sendmail is needed by (installed) lsb-1.3-191.5


What is smtp_daemon? I didn't see where this program got installed by
Postfix.
Is it is safe to run "postfix -e --nodeps postfix-2.1.1-1.4"

Thanks for your

Under SuSE, "smtp_daemon" is a reference for any one of these 3 RPM packages:
sendmail, postfix, or exim.

If you are going to compile Postfix source code and install it, I'd
probably leave the existing postfix RPM installed, and let the
"make install" overwrite it. But you'd have to take into account
not overwriting postfix whenever a new RPM becomes available.

The reason I'd overwrite it: if you remove the postfix RPM, then it will
remove the system startup scripts, and others.

If you are wanting to replace postfix with sendmail or exim, then you could probably
install the new RPM, and then remove the postfix RPM with no errors.
