Hi, i just installed postfix on my company and is working fine, now
the company management has asked me to
implement a group security model that i dont know if i could do it in
postfix, it goes like this :
1. We want to have a group of persons that can send and receive emails
without restrictions
Add them to a sender whitelist, with appropriate restrictions on the
client IP (or set up SASL/TLS for "road warriors").
Make sure to put this whitelist access map in front of any BLACKLISTS
you use.
2. We want to have a group of persons that can send and receive emails
but they cannot send attachments ( based on extensions .exe, .pdf,.xls
etc)
Probably best done with a policy server.
3. We want to have a group of persons that can only send and receive
internal emails.
Yet another whitelist, this time exclusive, in a restriction class to
capture both the sender and recipient addresses.
Can i configure postfix to handle that?
You can configure postfix to handle almost anything.
Mail-related.
