[NBLUG/talk] Configuring sendmail to forward email via sonic.net

[Todd Cary]

Ron -

Here are the changes I did make to sendmail.mc:

dnl #
define(`SMART_HOST', `smtp.sonic.net')dnl
dnl #

MASQUERADE_AS(`aristesoftware.com')dnl
MASQUERADE_DOMAIN(`aristesoftware.com')dnl
FEATURE(masquerade_entire_domain)dnl
FEATURE(masquerade_envelope)dnl

Not sure if the masquerade is necessary though.  However one of 
the areas where I have a lack of knowledge is setting up the 
hosts file.  Here is what I have:

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1    localhost.localdomain localhost
::1        localhost6.localdomain6 localhost6
127.0.0.1    localhost.localdomain    localhost    centos5
216.228.174.9    toddcary.com    localhost

However in the maillog file, one of the error lines is still 
having the ctladdr set to <root at localhost.localdomain>


Aug 24 12:47:10 localhost sendmail[2309]: r7LNUtVO020623: 
to=<todd at aristesoftware.com>, 
ctladdr=<root at localhost.localdomain> (0/0), delay=2+20:16:15, 
xdelay=00:00:01, mailer=relay, pri=6330367, relay=mail.sonic.net. 
[64.142.7.162], dsn=4.0.0, stat=Deferred: Temporary AUTH failure

Thank you for your resonse along with the others...
