Phil
Per our previous email discussions I have written
up a rough draft of Exim source quick install HOWTO
for two common classes of Exim users (1. clients
and 2. mail servers on isolated/firewalled LANs such
that less security concerns). I need some questions
answered from you and I need myself to test this
before releasing it as 1.0 version. The reason for
these questions is I'm trying to ascertain the
simplest Makefile usable for my class of users --
even simpler than the one in your O'Reilly book if
possible...
(Remember I am a NEWBIE trying to make this HOWTO
not a guru email manager. Remember this was
intentional.)
Q1. Is the EXIM_UID & EXIM_GID trick to avoid always running
as root useful/necessary if only running Exim as a client?
As far as I can tell there is no security risk with email if one
is NOT running exim daemon in background to RECEIVE emails.
Q2. Will exim default to using syslog with this minimal
Makefile or is "LOG_FILE_PATH=syslog" necessary? If
we don't use syslog then newbies need to rotate log files
which may give them a heart attack.
Q3. Are all the DIRECTOR_* variables in Makefile
absolutely necessary for client usage of exim???
Please explain their use in few sentences if so.
Is it possible to remove some or all?
What about LOOKUP_DBM and LOOKUP_LSEARCH???
Can you explain what *clients* need this for if necessary?
Q4: SPOOL_MODE=0600, LOG_DIRECTORY_MODE=0600
MSGLOG_DIRECTORY_MODE=0700 and
SPOOL_DIRECTORY_MODE=0700 all OK???
Can we get away with making all this stuff
NOT be group/world readable???
i.e. Will my 600s and 700s work????
Hope this helps,
Chris
