Hi,.
Scratch my last message for not being able to send to the outside
world... that was an LDAP issue - shutting off LDAP was the solution
- I can now email out (yeah for me). hehe... sheesh... only two
thousand options left to figure out!!
LOL LDAP seems to work for me under 1.5.1.3
ASSP is an excellent application... just lots of tweaking (for me anyway)...
Hey it allows you to do what you want and need to do. Once configured
it is WONDERFUL. It just hums. You can set it up to send you
summaries of blocked mail or if you are a hoster send each sub admin
their own reports! Cool.
I am still seeing the spoofing issue - shutting off the check
allowed things to pass through ok...
In order to activate the spoof check - do I have to force
authentication on 587?
I'll have to check if there are alternatives but everything we do
here is auth. If you have webservers etc you can whitelist by IP for
example.
I am trying to get this to work without Force SMTP AUTH... I have
many users I will be moving to assp - having them make a bunch of
changes to their email applications, devices etc. is not the
preferred method - but I am starting to think it is the only
method...
I am not sure how you can easily do that when they are logging in
from the outside world.
The biggest problem is that the outside world has become much more
hostile than when we all started. Breaking in and cooping has become
too widespread. I could probably come up with a way BUT it would be
easily spoofable.
Moving to auth now is the only safe way. Look at it this way you were
able to put off auth for a long time but the world changes and I am
sure that your users will understand the need for security, after all
it is their reputation as well.
