Hello...
I'm looking to implement an antivirus for SMTP together with IMail. Which
one do you think is the best.
Actually i've downloaded an evaluation version of the Norton one... Norton
AntiVirus 2.0 for Gateways...
Is there any other goodies like this available?
Which one do you prefer?
Thanks for your answers :-)
I plan to use it on a separated server dedicated to this.

How i want to stop the spammer from spam my imail server?
Please help...URGENT..
Faizal,
URGENT: what is he doing?
Go to controlpanel:Imail:SMTPSecurity:mailrelayoptions:relayforaddresses and
enter your blocks of ip's. then stop/start the smtp service. This is
immediately stop all mail relaying from ip addresses outside of your
"trusted" ip blocks. It is the best anti-spam setting for Imail.
If the spam is still getting through 1)somebody on your ip's is a spammer
(behead him), or 2) the spammer outside you ip block and is spoofing your ip
addresses.
Imail cannot fix either one of these.
For 1) use a dull axe
for 2) have your router dude block ip spoofing at your border router by
setting up packet filtering that drops (and logs) all packets on the
"outside" (incoming link, from your upstream backbone connection) interface
that announce themselves as coming from your "inside" ip block.
One "side effect" (there are ALWAYS side effects) of "relay for addresses"
is that your roaming users who try to send mail through your Imail are
actually relaying mail and will be blocked because they connect from outside
of your trusted ip blocks. So in their mail program, they must used SMTP
AUTH so when they send mail to your Imail, the "SMTP client" of their mail
program will AUTHenticate itself with Imail, which you must have set, in
SMTP security: Disable SMTP AUTH reporting "unchecked".
