RE: [cobalt-developers] Sendmail not reject email addresses

Not before you suggested it, but I have now and still no difference.

I am not to familiar with sendmail.

After modifying either the access or virtusertable files of sendmail, is
there anything else that needs to be done before I restart the service?

I am restarting sendmail via it's init script in /etc/rc.d/init.d/

I am wondering if sendmail on my XTR is jacked or not.

For example the status of my mail services on the XTR is

The Post Office Protocol (POP3) server has been running normally since
Wed 02 Jan 2002 02:15:06 PM PST.

The Internet Message Access Protocol (IMAP) Server has been running
normally since Wed 02 Jan 2002 02:15:05 PM PST.

The Simple Mail Transfer Protocol (SMTP) Server has been running
normally since Mon 25 Feb 2002 03:15:15 PM PST.


Now the SMTP uptime stats seem pretty accurate, my IMAP and POP services
have not been up since January.

I have restarted the machine at least twice since then.

In fact my XTR went into production on or about January 1, 2002 just
after it arrived. Immediately I had problems and I thought them to be
minor but looks pretty major.

Since at this point I am assuming on January 2 is when I first saw an
error with my email service on my XTR.

The only way I can replicate the error is if under the main home user
group I change any of the email settings for any user.

If I add or remove and alias, or attempt to modify the vacation message
I get the following error

4262 email_cant_buildhash

Hopefully someone from Sun/Cobalt will be reading this and look into the
matter.

For the record, I had not modified anything out of the normal at the
point that the error first occurred on January 2. So when the problem
occurred I had not done anything yet to violate my warranty.

Of course since then I have, but it did not affect my mail service,
since at that point something was already broke, or screwed up. 

Not a happy campier.
