Sendmail: did not issue MAIL/EXPN/VRFY/ETRN
 

Hi,

I am experiencing a little trouble setting up sendmail (8.12.11) on Fedora Core 2. A have a simple sendmail.mc:

divert(-1)
dnl This is the sendmail macro config file. If you make changes to this file,
dnl you need the sendmail-cf rpm installed and then have to generate a
dnl new /etc/sendmail.cf by running the following command:

The problem I am experiencing is in *sending* mail from a win2K (sp4) box. I receive mail properly. So, when I try to send mail (using Netscape mail v7.2), I get prompted for a password. I supply the same username/password that I can ssh into the linux box with. That fails to get authenticated, so after I cancel, I get this in /var/log/maillog:

<hostname> [192.168.2.2] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA

Now the funny thing is that I can send mail with Outlook express -- no problem.. I am guessing this has something to do with the authentication that sendmail uses. I sifted through sendmail configuration links on google, but couldn't figure it out. Could this be a FEATURE from my sendmail.mc that's missing or wrong?

Also potentially significant is that I have based my sendmail.mc (and .cf of course, that I got by running m4) on a RedHat 7.3 version that I rebuilt with Fedora Core 2.

I'm a bit stuck with this and will greatly appreciate any help..

Thanks,
Nenad

you're probably running the wrong ttype of auth encryption with netscape
