Subject: localhost.localdomain... example
Sometimes... BUT not all the time... my mail gets sent with the domain of
@localhost.localdomain

where do I fix this problem!

I have looked at sendmail.cf and cannot readily find the rule which governs this kind of problem... a lot of rules are close but none fit exactly.

What are the networking files I should look in?

Thanks for your help!

Lynn

HERE IS AN EXAMPLE......
