SendMail conf for use externa SMTP server

[Guillermo Garron]

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 at yahoo.com
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 at yahoo.com
with no good results,

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

after that is all ok, it is the same as if i configure my thunderbird to use
that server, with authentication
now loggin as root these are the results.

----------------------------------------
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?
