I am able to get SMTP AUTH running fine with Slack 9.0 box but with
Slack 8.0 box, I have some problem (please see the errors below)
Both are using cyrus-sasl-1.5.28, spammer.com is not in the /etc/mail/access or /etc/mail/relay-domains

I have managed to install and configured 3 Slack 9.0 boxes with
cyrus-sasl-1.5.28, sendmail8.12.9 with kernel 2.4.20.
Is there anything to do with the kernel? 2.2 and 2.4?

Now my slack 8.0 box is an open relay.
Hope someone can help before my server is listed in all the open relay database.

My sendmail SMTP AUTH is very erratic, sometime works, sometime don't

this is my /var/log/maillog file (I replaced the actual domain name with "domain")
