a spammer within your organization and/or within your ip blocks? What are
is your Imail "relay options" settting?

That's a very slow way to spam, may all your spammers be HTTP Web Mail
spammers!
>this is very unsecure.
They have to log in. If your own users are sending spam from Web
Messaging, then you have a social/political pb to which there is no
technical solution.

How many is that? Did they send it via Web Messaging or by SMTP sending
from a mail pgm?

You must use "relay for addresses" and SMTP AUTH in Imail and in the mail
client to protect your server. SMTP AUTH requires the sender to provide
valid accnt name and password before relaying mail through your
server. But if your own people are spamming using their accounts on your
server, then you should study your logs carefully to see what account they
are using (requires you to have SMTP AUTH activated).
>then my supervisor went off
like a firecracker??
>and said how can we trust IMail...
All e-mail, unencrypted, is as secure as postcards. Imail can be set up to
defend against spamming. Just Do It.
>how can we keep using this mail server...
follow the rules
> we should switch.....
Don't swtich, fight!
>Does anyone know what alternative mail servers are out there?
There are lots of alternatvie and they are all attacked by spammers.
You need to install technical spam defenses of Imail and have Terms of
Service for your users that forbid spamming and then kill their account if
they violate those terms.
>I'm sure switching server won't solve the open relay hole problem.
No, there a 10's of 1000's of open relay mail servers out there and they
are not all Imail.
Now, you say you're running Imail as open relay? Don't do that.
>But if anyone can help, much appreciate! thanks! ^_^'
Close your open relay.
