Limitation for E-Mail sending

[yogg1]

Hi

Is it possible to configure zimbra that mails can only be sent from internal ip addresses (WebMail)?

The problem:
If an spammer finds out an weak password he can send all his spam over this server (office@example.com password: office EIFOK ).

I know it is easy to set up password rules, but not alwasy it is possible for me to do this. And it will also not help if an spammer finds out an "strong" password.

A workaround would be to limitate the number of E-Mails per hour (50). Is there a way to do this?

Search the wiki, forums or google for the word 'policyd'.

Thank you the searchstring helps

Sadly the workaround this would only helps against DOS :/ .

Is there no way to add an check if the user is in the internal network? If this chek only works for SMTP (not the WebMail) it would be ok.
