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".
