Hello list, I am trying to rewrite the sendmail rules to present my correct email address when a message is sent to the ISP. I took a look at the address rewriting mini howto on how to do this at <http://www.linuxdoc.org/HOWTO/mini/Sendmail-Address-Rewrite.html> but I get the following error when I hash the aliases file using newaliases. # newaliases /etc/mail/sendmail.cf: line 43: unknown configuration line " " I took a look at the 'sendmail.mc' file but can not find anything wrong. The m4 macro processor does not give me any complaints. I have included the file below. Thanks in advance for any help.
