Full Discussion: sendmail : 550 host unknown
Top Forums UNIX for Advanced & Expert Users sendmail : 550 host unknown Post 10214 by Neo on Friday 9th of November 2001 11:48:36 AM

Because of this:

Code:
server# nslookup
> set type=ANY
> sharkms.ch
Server:         64.23.27.23
Address:        64.23.27.23#53

** server can't find sharkms.ch.: NXDOMAIN

So, it is not possible to send any mail to sharkms.ch because it is not working in DNS properly as a FQDN.

What is the nameserver IP address for sharkms.ch ? We will check this for MX records and other problems (if possible...)
