RE: [SLUG] Sendmail quirks

The way I test it I usually use nslookup.
So if the email is going to balhuser@xxxxxxx I try the following

[georgev@citadelserver georgev]$nslookup
Default Server:  dns.blahblah.com
Address:  203.x.x.x

> set type=mx
> foo.com
Server:  dns1.blahblah.com
Address:  203.x.x.x

        origin = ns.okdirect.com
        mail addr = namemaster.okdirect.com
        serial = 1
        refresh = 10800 (3H)
        retry   = 3600 (1H)
        expire  = 604800 (1W)
        minimum ttl = 86400 (1D)

If this fails then there's your problem. I also had some weird problems when
/etc/resolv.conf had permissions of 700 and for tests I changed it to 744
and it worked OK and services like squid and others started to work again.
Sendmail might be having this problem too.??..??..??

Just out of interest what is a nullclient cf setup look like and what does
it do?
