This could explain why I have been having receiving console
error messages up the ying yang : I was previously advised
to change the sendmail.cw file (as opposed to simply adding
lines to Cwlocalhost) so that I actually have :

[snipped from sendmail.cf]

        ##################
        # local info #
        ##################

        Cwlocalhost
        # file containing names of hosts for which we receive email
        Fw-o /etc/sendmail.cw

        # my official domain name
        # ... define this only if sendmail cannot automatically determine your domain
        #Dj$w.Foo.COM

[/snip]

and the following in sendmail.cw :

        aaa.com
        bbb.com
        ccc.com
        mail.aaa.com
        mail.bbb.com
        mail.ccc.com

This seems to work (although I am unsure if both aaa.com and mail.aaa.com
are needed) but I would like to get rid of the console error messages.
And lately , there have been a lot of people timing out
while trying to check mail.

So, can I assume that it is not enough to add the
domains to sendmail.cw but that the Cwlocalhost must be
added too ?


I am actually trying to run a mailhub which
handles the mail for several virtual domains whose
webservers are running on a separate machine :

machine 1 : machine 2 :
---------- -----------
mail.aaa.com aaa.com
mail.bbb.com bbb.com
mail.ccc.com ccc.com

If possible, could someone pls confirm whether the
following is the correct DNS set up for the above :

[zone file for aaa.com]
;
aaa.com. IN SOA neuronet.com.my. postmaster.neuronet.com.my. (
                     23 ; Serial
                        300 ; Refresh - 5 minutes
                        60 ; Retry - 1 minute
                        1209600 ; Expire - 2 weeks
                        43200 ) ; Minimum - 12 hours
;
                        IN NS neuronet.com.my.
                        IN NS relay1.jaring.my.
                        IN MX 10 mail
                        IN A 202.184.153.4
www1 IN A 202.184.153.4
www IN CNAME aaa.com.
mail IN MX 10 mail
mail IN A 202.184.153.15
; %HOSTS_END%


(DNS is run on a third machine and i do realise that
it may be preferable to run it on the same machine
as the mailhub)

If I have made a boo boo in any of the above, pls do let me know.

Thank you very much in advance,

chas
