# You must replace "xmail" and "XMAIL" with the lower case name and
# upper case name of your new package.  Some places below will say
# "Do not change this" - that does not include this global change,
# which must always be done to ensure we have unique names.

# paulhar NOTES
# 1) When the package is removed, I can't understand why it doesn't remove
#    everything it installed. e.g /opt/var/MailRoot
# 2) For any form of logging to work syslogd needs replacing; the native one
#    doesn't appear to write any logs. This should be double-checked by someone
#    other than me since I've just replaced mine :)

#
# XMAIL_VERSION, XMAIL_SITE and XMAIL_SOURCE define
# the upstream location of the source code for the package.

# archive is unpacked.
# XMAIL_UNZIP is the command used to unzip the source.
# It is usually "zcat" (for .gz) or "bzcat" (for .bz2)
#
# You should change all these variables to suit your package.
