sendmail relaying
 

Hello,

Would anyone be willing to help me resolve this problem or refer me to a good how-to detailing it? I wish to configure Sendmail to allow authenticated users to send e-mail. I have disabled the localhost only option,


dnl # DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

but now run into errors in Outlook Express

Server Response '550 5.7.1 <emailadress@somewhere.com> ... Relaying denied. Proper Authentication required

OE is configured for outgoing, plain text mail authentication. I've tried it with SPA and SSL, but those failed as well.

I have verified accounts and passwords

sPOP runs just fine so I'm doubly sure the account is setup properly.

My ideal is to configure a secured SSL or SPA outbound authentication, but would greatly appreciate knowing how to do this plain text as well just in case the more sophisticated methods fail.

I have also change sendmail.mc to include the following:

TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl

define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')

I'm using Fedora Core 2.

After changing my sendmail.mc I do:

m4 sendmail.mc > sendmail.cf
and
make
newaliases
/etc/init.d/sendmail restart

I have started the saslauthd service.

Thanks in advance for any assistance.

Ben,

Could your ISP be blocking outgoing port :25 traffic? I know mine does - I had to configure sendmail to relay through my ISP, but once I did that I had no problems sending out emails.
