here go few ideas.
well, I stick to UUCP, because I'm using it.
the goal:
=====================================================================
to have actually 4 domains (domain.com.br, locX.domain.com.br where
X=1,2,3).
site domain.com.br is online 24hours. sites locX.domain.com.br could be
offline, all mail will be collected at domain.com.br anyway
the all 4 domains are administered independently (local roots can add
new users at locX.domain.com.br without anybody knowing).
=====================================================================
I hope 'domain.com.br' is registered domain.
1. ask you provider (or did it youself) to add MX entries for
locX.domain.com.br (like it's done for cgilh.chel.su or for
jane.cgu.chel.su, just type "$ host cgilh.chel.su").
2. on machines locX.domain.com.br add the following line to
/etc/mailertable
-------------------------------------------------------------
.domain.com.br uucp-dom:domain
domain.com.br uucp-dom:domain
. uucp-dom:domain
-------------------------------------------------------------
do not forget to !!
"makemap hash /etc/mailertable.db < /etc/mailertable"
3. on machines locX.domain.com.br adjust /etc/uucp/*
to 'call' goes
------------------------------
domain UlocX locX-passwd
------------------------------
domain - UUCP-name of domain.com.br
UlocX - UUCP-account at domain.com.br (I'll tell you later)
locX-passwd - clear-text password for that account
to 'config' goes
-------------------------------
uuname locX
-------------------------------
where locX - is UUCP-name of locX machine
to sys goes
-------------------------------
#
# domain.com.br
system domain
called-login *
time Any
port type TCP
address domain.com.br
chat ogin: \L word: \P
-------------------------------
4. on machines locX.domain.com.br
also adjust sendmail configuration, make domain.com.br as SMART_HOST
(just adding DSdomain.com.br to /etc/sendmail.cf should be enough)
now I'll try to describe setup at domain.com.br, it's more tricky
cause I'm not running the server :-)
5. you should create UUCP-accounts for each machine,
something like (/etc/passwd)
UlocX:*:2014:66:UUCP account for locX
machine:/tmp:/usr/libexec/uucp/uucico
one UID, GID should be enough, do not forget to set those passwords
(from /etc/uucp/call on locX)
6. /etc/mailertable on domain.com.br
-----------------------------------
.locX.domain.com.br uucp-dom:locX
locX.domain.com.br uucp-dom:locX
-------------------------------
7. probably you need to adjust /etc/uucp/passwd on domain.com.br,
but I'm pretty sure we didn't do it.
8. since all the mail is to be collected at domain.com.br, you need
to 'fetch' it to locX.domain.com.br,
do it with (on locX.domain.com.br)
$ /usr/libexec/uucp/uucico -S domain
9. all the messages about errors you can find at /var/log/messages
and at /var/spool/uucp/Log
10. let me know how it worked for you !
make sure your sendmails understand /etc/mailertable !
did I miss anything ?! anybody, correct me.
Regards, (Наилучшие пожелания)
