Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Sender: owner-isp@freebsd.org X-Loop: FreeBSD.org Precedence: bulk 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.

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
