sendmail & masquerading problem

[Luca Ferrari]

Hi,
I've got a mail server running sendmail 8. I'd like to masquerade 
machines behind the mail server, thus e-mail does not appear to be sent 
from machine.mydomain.com but only from mydomain.com. I've tried the 
masquerade directive as follows, but it does not work. Any suggestions?

dnl MASQUERADE_AS(`mydomain.com')dnl
dnl FEATURE(masquerade_envelope)dnl
dnl FEATURE(masquerade_entire_domain)dnl

Luca,

I take it you are running your .mc config file though m4 to create a 
new .cf etc...

How is it showing up as not being masq'ed ?

Have you tried MASQUERADE_DOMAIN against a particular host that is 
not getting automatically masq'ed ?


Regards
Carl

"dnl" deletes everything up to the end of the line. If you place it at
the beginning of a line, the line will be ignored (similar to
"commenting out" a line in a shell script by placing a "#" at the
start of a line).

Apart from that, you have to tell it which domains to masquerade via
MASQUERADE_DOMAIN or MASQUERADE_DOMAIN_FILE. Otherwise it will only
masquerade domains in class w (i.e. any aliases for mail server itself).
