In order for sendmail to find a particular hostname, it looks up the mail delivery (MX) record so start with: nslookup -type=mx asl.srv

If this fails, your DNS server is not providing MX records and you'll have to put this server (perhaps others) into /etc/hosts. Then change /etc/nsswitch.conf hosts entry to look like this:

hosts: files [NOTFOUND=continue UNAVAIL=continue] dns

Also edit two files in /etc/mail: sendmail.cw and services.switch. In sendmail.cw, the end of the file should look like this:

localhost
mycomptername

and service.switch:

hosts files dns
aliases files

Then restart sendmail:

/sbin/init.d/sendmail stop
/sbin/init.d/sendmail start

Shalom,

Diags:

sendmail -v -d8.99 -d38.99 someaddress@some.net

type some text

.

full diags from this.

also:

sendmail -v -q

This will run the queue.

Without host name resolution the only way to get mail delivered will be to use the DS directive and relay the mail via another server.
