I have set up a mailhub for virtual email domains on
a FreeBSD box. This machine is a P166, 64 MB RAM
and only runs the email servers (no web, ftp etc)
and only has 5 virtual domains. (with a total of
100 email accounts)
However, some people are having difficulty getting to
their email .. claiming that they get timed out.
The weird thing is that when I ping the machine over
our LAN I _always_ get timed out on the first ping, then
it is OK.
ie.
# ping mail.domain.com.my
Request timed out.

I have set up the virtual domains using the modifications
to rule S98 of sendmail.cf and can only guess that my DNS
is the problem.
This is the zone file for one of the domains whose
mail is being handled by the mailhub :
;
; Data file of hostnames in this zone.
;
domain.com.my. 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 domain.com.my.
mail IN MX 10 mail
mail IN A 202.184.153.15
; %HOSTS_END%
Have I made a boo boo here ?
Or could it be due to the DNS being on a separate machine
(DEC 500 with 64 MB RAM), handling 60 domains as well
as 2 webservers ????
Cheers,
Chas
ps. I trust that it is not due to the following mods. I made
to the sendmail.cf file :
[snip]
Cwlocalhost
Fw-o /etc/sendmail.cw
[ ....]
S98
R$+ < @ $+ . > $: $1 < @ $2 > .
R$+ < @ $+ > $* $: $(maildomains $1@$2 $: $1 < @ $2 > $3 $)
R$+ < @ $+ > $* $: $(maildomains $2 $: $1 < @ $2 > $3 $)
R$+ < @ $+ > . $: $1 < @ $2 . >
[/snip]
and then sendmail.cw has the domains for which i'm collecting mail:
cyclops.com.my
mail.cyclops.com.my
heaven.com.my
mail.heaven.com.my
peace.com.my
