Sendmail adding local domain to From field

Sendmail adding local domain to From field


I have a problem with sendmail leaking information regarding the local domain of the server.

In the file I have the following line: define(`confDOMAIN_NAME', `www.somedomain')

In the file I have the following line

# my official domain name
# ... define this only if sendmail cannot automatically determine your domain

Now sometimes what happens are mails are sent out using the following format:
sendmail -i -t -v
From: "Dan" <>
Subject: test
Some email body.

So when it gets to the recipeint you find that the from address has been translated (assume the local domain on the server is to From: "Dan" <>, but this does not happen on every mail sent and I think it depends on what server it is sending to.

However I need to stop sendmail from leaking this information.

Does anyone know what the problem could be or is the config file misconfigured?

thanks in advance
