accept emails only from accounts on server

[MACscr]

OK, so i setup the spam and ham email accounts, but I only want to accept email to them from either only accounts on the server or a txt file of domain names. I obviously dont want spammers to be able to send email to my ham email account. Any ideas on how i could accomplish that?

Thanks, its sad that there isnt a method that can survive upgrades (according to the wiki) though. I am using the network edition if that makes any difference.

True; though this is why the default configuration for Zimbra is to obfuscate those addresses.

Which we all know that obfuscation != security. Plus like I am going to expect everyone to have that address memorized or in their contact list. So that style is very unfriendly. I am quite surprised the outlook connector doesnt have buttons for training spam/ham as well. =/

Uh, I do not see a spammer trying hundreds and thousands of emails; plus if using something like Greylisting or OSSEC you could always block them after a number of failed attempts.

Hmmm, why would your users need to remember the addresses ? You could always share those folders to your users and allow them to drag 'n' drop emails into them as a thought.

No need to share folders. Every user account has a Junk folder. Dragging an email into or out of the Junk folder automatically forwards it to the spam or ham account as appropriate.

This has been standard behavior for a long time (5.0.11 I believe). See Bug 9532 – IMAP/Outlook move to junk doesn't train anti-spam

In Outlook, unfortunately, there's no single button that moves an email into/out of Junk, but dragging works fine. You can also right-click and use "block this sender" but this is somewhat misleading, as the sender isn't blocked although the mail does get put into Junk, which triggers training.
