Hi all,

I have a laptop with FC5 and wanted to use it as my smtp server and also
wanted to receive my logwatch reports each day.
the problem is that because all the battle against spam my laptop is no

accepted almos anywhere so i start to configure my sendmail server to use an

externet smtp server.

I followed this steps
___________________________________
Step 4: add to your sendmail.mc in /etc:

   FEATURE(`access_db')dnl
   FEATURE(`authinfo', `hash /etc/mail/authinfo')
   define(`SMART_HOST',`outgoing.verizon.net')dnl
   MASQUERADE_AS(verizon.net)dnl
   FEATURE(`allmasquerade')dnl
   FEATURE(`masquerade_envelope')dnl
   FEATURE(genericstable, `hash -o /etc/mail/genericstable')dnl
   GENERICS_DOMAIN_FILE(`/etc/mail/genericsdomain')dnl

Step 5: copy the entire sendmail build subdirectory sendmail-8-13.2/cf/cf to

/usr/share/sendmail-cf/

Step 6: m4 /etc/sendmail.mc > /etc/sendmail.cf

Step 7: add the following lines to the files /etc/mail/access,
/etc/mail/authinfo, /etc/mail/genericstable, /etc/mail/genericsdomain

   access
       From:ME at verizon.net             RELAY

   authinfo
       AuthInfo:outgoing.verizon.net "U:ME at verizon.net"
"I:<MY_VZ_ACCOUNT>" "P:<MY_VZ_PASSWORD>" "M:LOGIN PLAIN"

   genericstable
       <MY_LOCAL_NAME> ME at verizon.net

   genericsdomain
       localhost.localdomain

Step 8: make the db files:
       makemap hash access.db < access
       makemap hash authinfo.db < authinfo
       makemap hash genericstable.db < genericstable

Step 9: /etc/init.d/sendmail restart

Step 10: test by:

   > sendmail -bv ME at verizon.net
     Notice: -bv may give misleading output for non-privileged user
     ME at verizon.net... deliverable: mailer relay, host
outgoing.verizon.net, user ME at verizon.net

step from 1 to 3 are compiling the sendmail server, mine is already compiled

even witch sasl support, ok, once i finished this steps i try to send an
email from the console using this

mail me@xxxxxxxxx
it worked since i was logged as my user in my laptop

i realized that the emails send by root was not able to go out, and receive
a Domain not found error
i tried logged as root
mail me@xxxxxxxxx
with no good results,

this are the logs at my external smtp server using my user and root.

----------------------------------------
As you can see now it does not authenticate as my user on that server, and
is not uses SASL method, not even trying to login

can anybody help me please?

You could try removing:

EXPOSED_USER(`root')dnl

from your sendmail.mc, rebuild sendmail.cf and restart sendmail.
