mailx -r not working

[daljitsingh]

I am able to use mailx -r "return-address" on one machine (SunOS machine1 5.8 Generic_108528-09 sun4u sparc SUNW,Ultra-2) but not another (SunOS machine2 5.8 Generic_108528-08 sun4u sparc SUNW,Ultra-80).

machine1
echo " " | mailx -r "support@company.com" -s "Customer response" customer1@a.co.uk

result : return address on Outlook message is support@company.com

machine2
echo " " | mailx -r "support@company.com" -s "Customer response" customer1@a.co.uk

result | return address on Outlook message is login@machine2.dns.domain

Can anyone help and tell me how I can get mailx -r working on my machine 2, i.e. is there some configuration on that machine or perhaps on the accepting email system ?

Thanks in advance

Just a guess, but machine2 seems to be trying to gain access to a DNS (Domain Name Service).

Normally, you need to tell each machine the IP address of a domain name server, which performs all those name-to-IP translations.

Can machine2 even see the internet at all?
